My OS is Windows 7 and I am having a problem with the miniature preview windows which pop up when you hover over an item(s) in the taskbar. A few days ago everything seemed to be working fine; i.e. as long as you continue to hover over the taskbar icon the mini-windows will continue to display. But now if I hover over a taskbar item the mini preview window will display but only briefly - it will disappear sometimes after 0.5 seconds, sometimes after 3 seconds, etc, but I don't think I've ever seen it stay up for more than say 10 seconds.
I also have the exact same problem when using ALT+TAB to view all the mini-preview windows.
I've tried disabling Aeropeek; and I've tried changing my 'Personalize' theme to Windows Classic, but neither helped.
Has anyone else experienced this? And were you able to find a resolution?
