MS Wireless Laser Mouse 5000 periodically becomes slow, jerky and unreliable

Just in the last couple of days, my mouse - a Microsoft Wireless Laser Mouse 5000 that I've owned for about a year and have until now been very happy with - has developed some strange, intermittent problems. Every so often, for no obvious reason, pointer movement becomes slow and jerky and it starts ignoring the majority of my clicks - I typically have to click the button three or four times to get it to register even a single-click. The one thing that works pretty much as expected at such times is the scroll wheel.

The problem is intermittent and unpredictable. One moment it will be as smooth as I could ask, the next it's an exercise in frustration to do the simplest tasks, then eventually the problem vanishes, as suddenly and mysteriously as it appeared. I'd say this happens about once an hour, maybe a little less, for anywhere from about 3 to about 20 minutes at a time.

I changed the batteries, then (several hours later) installed the software from Microsoft's site rather than just using the driver that comes with Win7 (the latter advice was from a similar thread from this site). Neither has helped; the problem still comes and goes as it pleases, not noticeably more or less often than before. At times when this happens, the wireless signal is (according to the aforementioned software) very good, and CPU activity is usually not particularly high, so neither of those things is the problem either.

Any ideas?

    My last post indicated the problem was solved by moving the receiver from the rear of the Desktop computer to the front. NOT QUITE. Yes there was a big improvement. However every now and again the intermittency would appear and each time after banging down the mouse down on the desk,on one side, the problem would go. That indicated some poor connection. The most likely area of bad contact is at the batteries. I tried silver conductive paint on the contact springs, no real improvement. I dismantled the mouse (four screws hidden under the two slide strips) All the wire battery connections to the printed circuit were resoldered. Had great performance since.

    Running on one battery is not the answer.

    Software can cause problems but in general a jerky /intermittent movement can be considered as an unreliable wireless link, low or momentary loss of signal.

    To summarise

    Keep the signal strong with the receiver close to the mouse (reduces risk of interference)

    Check for an internal intermittent connection as above and fix if necessary.

    MICROSOFT take note.

    I support GilesConstant.

    Having spent about two months trying to fix the Wireless Mouse 5000 problem, much of that time with Microsoft support. Before contacting Microsoft I tried all the obvious mouse specifics, batteries, interference and drivers. Then I tried many other tests.

    The problem proved to be independent of operating system, security software, batteries and other USB hardware. At one stage I had a marked improvement by installing a completely different architecture graphics card, within seven days the problem re-emerged.

    The problem has been finally solved. I had been very misled by the Microsoft claim of a 30ft wireless rangeand therefore did not consider there would be an issue in this area. WRONG, by moving the receiver from the back of the Desktop computer to the front the problem disappeared. This move removes the case metal shielding of the receiver, raises the signal level to the receiver above a marginal level which in turn will reduce the prospect of interference.

    The two batteries in the mouse are connected in parallel to double the battery life, removing one will simply halve the life, as to why this might improve the mouse operation one can only guess that somehow this changes the RF signal level/pattern by a small amount and thus moving away from an otherwise marginal signal condition that will result in variable operation.

    I have now discovered others who have moved the receiver to the front get the same result, therefore my advice is that this should be the first move in correcting the problem.

    This probably sounds obvious, but nobody else has said it!  I had the exact same problem, and it got worse and worse over time.  I tried updating the BIOS, updating drivers, etc.   Then realised the obvious.  It was a signal strength problem!  It's WIRELESS, remember?!   this is how I fixed it..

    1. Make sure mouse is near enough to the dongle (I moved it from the back to the front of the PC)
    2. Make sure it's got fresh batteries in it

    doh!

    My mouse inexplicably developed the same problem - no warning whatsoever.

    I finally realized that the problem developed when I began installing rechargeable batteries in the mouse.

    Switched back to regular alkalines, and problem disappeared.

    Whoever marked the BitDefender thing as an answer shouldn't have. This is not the first time I've seen a complete non-sequitur marked as an answer. Whoever does this, please don't presume to speak for the original poster about what solutions do and don't work. I have never even USED BitDefender, and I explicitly stated earlier in the thread that the most closely related steps that did apply to my situation had been tried and did not work.

    (I have unmarked it now - a course that wasn't available on the previous occasions when this happened.)
