I'm going nuts trying to debug this problem.
I don't think its related to any software I installed (using My uninstall, nothing was installed new before this problem but roboform, and it is safe to assume RF is not the culprit).
The strange behavior I find is that any new window will cover the taskbar, and initial size is not full screen(but a strange long rectangle).
I have my screen not in landscape mode, but vertically. The drivers for ATI radeon 9000-laptop take care of this. It worked fine until now. The windows taskbar is on top. Moving it to any other position didn't fix it.
Rebooting doesn't solve it
.
Changing the properties of the taskbar (make it on top of windows) doesn't help, because it covers the top part of any window that is maximized, losing info.
The problem is that the taskbar window does not block others to cover it. It works as if the taskbar coordinates are ignored by the system.
I have searched annoyances.org, but couldn't find any related solution.
Any ideas about what to try?
Thanks
