When I hover over the icons on the task bar, I usually see thumbnails of the programs I have open. Today it is flashing those thumbnails very fast and then nothing. How can i determine if this is a conflict caused by a program I installed yesterday? The way I am getting IE8 to come back up is I am right clicking and selecting a "recent" page and it will come up. Otherwise I am not able to get IE8 up, even though it is actually launched and I have severla tabs up. Same thing with Outlook, Excel, each of which I have open, but I cannot navigte back to the open windows.
