Mouse stickiness change with multiple monitors after Windows 8.1 Update 1: Bug or feature?

That's interesting, I wish I had another monitor so I could try it out.

I have one guess based on the new behavior of the taskbar though.  Try this:  go up to the edge, and stop, then move through the break again.  Basically go up to the edge, pause, then push past it.

The new taskbar behavior is like this. If you move to the bottom of the screen completely, the taskbar doesn't appear, but then if you push again (not back up and go again fast, just continue pushing the same direction after a brief pause) it will show up.  I'm curious if the monitors do this too.

I have 3 PCs/Laptops set up with dual monitors (1 to TV) and unfortunately I cannot duplicate your problem, all flow thru each monitor seamlessly.

I accept that this does not solve your problem, but it does not appear to be a general W8.1 bug,

Question: Are your monitors of the same specs (Resolution, touch or non-touch)?

Try this:

Go to 'Display' - 'Screen Resolution' and ensure the monitors are aligned side by side correctly, as they are physically in front of you. Once they are set up correctly select 'Apply"

Where ever the two monitors touch, is where they will allow the cursor to move between the screens

I hope I have explained this OK.

Hello,

Thanks for the quick reply. I tried what you suggested, and it still does not work, unless I go through quickly. Compared to showing the taskbar while in a Metro app, I have to apply a relatively faster speed to move my cursor to the other monitor.

Upon trying to duplicate the problem, I found out that this only happens sometimes. The only requirement for all instances that occurred was to have a Metro app running.

There are a couple ways to duplicate this problem.

The easiest is to open a Metro application, and try to drag it to another screen. You will see the issue that I linked to in my original post.

A second way is to swap from desktop to a Metro application. It does not matter how you do it. While the header bar is displayed, the issue will occur. When it disappears, the issue also disappears.

The above two ways don't always work, but when trying it, the issue happened most of the time.

Playing around with the issue, I realized that I need the same amount of mouse speed to go to the other monitor when the "Task Manager" or Charms bar is open.

From this, I deduce the issue has to do with the new header bar in Metro applications and the protection of the mouse going onto the other monitor while the "Task Manager" or Charms bar.

I believe Windows 8.1 Update 1 is falsely detecting that the "Task Manager" or Charms bar is open, and it is prevent my cursor to go to the other screen unless I apply a reasonable amount of speed.

I hope this helps the people that fix these issues,

Hello,

I have double checked what you suggested and it is unfortunately aligned. Although I have found some things upon further testing. I'd also like to reiterate that this happens only after the latest Windows 8.1 update, Update 1

Hi.

I can confirm this issue. I have 3x monitor and I just updated to W8.1 update ~1 hour ago.

As soon as I went to desktop and opened something, I was trying to move it to another monitor and faced this issue.

Behavior BEFORE W8.1 update (i.e., w8.1):

there is a small area from top and bottom (~100px height) of each left/right edge of all monitor where your mouse cursor will get stuck if you are moving it slowly. This has been done (on Windows 8.1) to help activate charms for mouse users.

Behavior AFTER W8.1 update (I.e., w8.1u):

1. The stickiness level has been increased a little
2. The small area (~100px height) has been changed to 100%.

#2 is the real culprit. This is almost a deal breaker. I am having SERIOUS issues moving windows from one monitor to another. And often, the cursor would just get stuck in the edge while going from one to another monitor just because im not moving it really fast.

Ideally, I'd like an option somewhere to configure the stickiness and height of that area.
