Ok - I'm not sure where to put this, but since the only thing in common is Windows, here it goes - please, as always, bear with me.
I got a new monitor for Christmas - a Viewsonic 23", VP2365wb. I hooked it up, popped the accompanying CD in the drive, and installed drivers. Well, in my hurry I did a 'complete' installation, which included a "suite" that seemed to have limited or no use for me. But that wasn't a problem, I figured, so I left it in place.
The first problem cropped up when my wife used the computer for the first time - she switched over from my account to hers (Windows XP Pro, SP3) and the mouse refused to do anything. This had never happened before. All we could do was a hard reboot, and the mouse worked fine for her, and when I logged into my account later, it worked for me as well. This didn't seem to be a major disaster, but a hard reboot in order to switch users? Not too handy, especially since every time it happened, I lost all my Firefox (v3.6) tabs and had to rebuild them each time.
I went to the Logitech website and installed the latest version of SetPoint, thinking that might be the problem since I hadn't updated the mouse drivers in quite some time. I also uninstalled the Viewsonic software, since a) that was the only new software change, and b) the installation didn't go completely smoothly; at the end the screen locked up and I had to do the 3-fingered salute to get the window to close. But then I've never had a smooth Viewsonic software installation in the past, so at the time I wasn't surprised. But that seemed to do the trick, and now we have no more mouse problems.
But then I noticed the issue I am having now - in any application or browser I use, with window maximized, the bottom edge of the window extends past (behind) the Windows taskbar. Resizing the window and then re-maximizing doesn't do anything, and the right-margin scrollbar down arrow is obscured by the systray clock.
I've scanned for viruses and spyware, and found nothing amiss; my screen resolution is what Viewsonic recommended (1920 x 1080); and the only software change I've made so far this new year is the "upgrade" from Firefox 3.6 to 9.0 - which means that now I get to enjoy multiple daily crashes in addition to slower graphical builds. I don't know if FF would have any effect such as what I'm experiencing, but I'm sick and tired already of not seeing the bottom of my windows and the sometimes necessary message bars located there. I have to scale down my windows and move them around on the screen in order to get a glimpse of the bottom of the window.
