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

I found the Problem.

It was the polling rate of the mouse!

At 1000Hz is was hard to get to the next window, while dragging a window,

at 250Hz it is perfekt for me. 

Hope it helps you :)

The gadgets from sides or  "configuration menu" is gone, for me is perfectly fine , hate metro.

It's a feature as outlined in this article:

"A multi-monitor setup brings the major benefit of more real estate, but it also lacks the Fitts' Law benefits of hard edges and corners across displays. While it’s extremely easy to trigger corner UI such as Start, charms, or recently used apps on a single monitor, it isn’t uncommon to overshoot the mouse when the corner appears on a shared edge on a multi-monitor configuration.

With multiple monitors in fact, targeting the shared edge can be downright difficult. Move a few pixels too far and your cursor is suddenly on the wrong monitor. This has been a common challenge in previous versions of Windows as well, like when you’re trying to hit the close button or scroll bars on a maximized window on a shared edge. Many work around this by remembering to move the mouse slowly as it approaches a shared edge or by avoiding window layouts that bump up against those edges. We commonly observe this behavior in our own usage and in field studies.

In the Release Preview, we’re introducing an improved model for shared edges that makes it easier to target UI along a shared edge.

Since corners are even more important for Windows 8, we’ve created real corners along the shared edges to mimic the Fitts’ Law advantages of a single monitor. The red corners in the diagram below demonstrate how these corners can help guide your mouse..."

Hello, 

These are all non-answers.

And why is a monologue post voted as the most helpful?

This "feature" is ANNOYING.

I never use Metro apps. This is computer and needs a computer OS; not this Windows 8.1 Pro Tablet  Hipster Metro Interface OS. 50% or more Windows users STILL use computers not tablets to get work done.

I have a laptop and three large external monitors.  Anytime I move the mouse between them I must wiggle the mouse back and forth several times to get it across the sticking threshold.

Sometimes it works if I go very fast, but that's inconsistent.

Here are some answers (solutions), which all involve registry editing*:

Thank god Microsoft doesn't own Google, or we'd never find the answers to this (based on Microsoft's massive response to this thread).

* Regsitry Editing: Why The Fish can't Microsoft make this an on/off feature when looking at multiple monitor settings?

Total Tangent: Why did Microsoft cripple COMPUTER users with a tablet interface OS? Why not make Windows 8.x for computers and Windows 8.x T (for Tablets)? This would let COMPUTER users/workers skip the entire Metro interface BS.

I've been a Microsoft user since Dos 3.0 and have literally used every Windows version since the beginning. I'm a developer and I bought an iPad Air for testing apps. I wish I'd been using Apple all these years instead of paying for one of Bill's Mercedes.

This isn't absolute, and there are exceptions, but generally when a Windows version is finished ("RTM" as it were), the duties of maintaining it get passed on to the ongoing maintenance delivery team, and they only change code if it is a security vulnerability or causing a crash.  Undesirable behavior generally doesn't get touched (unless it is causing a crash or security issue), which is how those hangnail-like annoyances that every version tends to have will remain (such as Windows 7 explorer jumping the scroll position to a terrible location but at least in that case, Classic Shell comes to the rescue).

But yeah, for the most part any change in actual behavior, even if it's an all out bug, are probably not coming until the next major release.

Maybe they'll surprise us though.
