Blinking Windows on the Desktop

more options

Computer Dell Vostro 1510 with 2 GB RAM Operating System: Windows XP with all service packs and updates

Recently I installed/updated Firefox to the latest beta version. That went well. The following day, I booted the laptop and windows on the desktop blinked in and out and shrank in size. If I double clicked on the shrunken window it would open and I could do some input. As long as the mouse pointer was on that window I was fine. If the pointer strayed away from that window or I had to go to another open window, the the blinking and shrinking would re-start.

I did check for viruses and malware and none were found. I have had this happen in the past with another beta version of FireFox and the only solution was to remove it. Firefox was never opened during the sessions.

That's very strange. If you check the Task Manager (Ctrl+Shift+Esc > Processes tab), if Firefox.exe running invisibly? If not, it's hard to see how Firefox is involved. ???
