My mouse wheel doesn't work on the left of my computer screen: I can't go up nor down using my mouse wheel when my cursor is hovering a strip which width is about from 5% to 30% from the left of my computer screen. From 0% to 5% and from 30% to 100%, it works though. Moreover, only the scrolling functionality of the mouse wheel does not work, i.e. the wheel-click works.
Any idea what could be the reason of that strange behavior?
I'm working on Windows 7 x64 bits. I already tried many mouses, but the problem still exists (i.e. it's not a problem with the mouse I'm using).

I've had something remarkably similar to that happen with pidgin in the past, though the problem showed up in a different manner - fullscreen didn't work correctly in my case.
Quite simply you have an application that is docked but somehow is invisible, but your system knows its there and acts accordingly. As such, your mouse is acting on the invisible application rather than the visible one. A quick fix would be to kill the application from task manager and restart it. Pidgin eventually fixed that bug, so chances are once the devs work out its a problem, it will be taken care of.
