[SOLVED] Window flashes in taskbar

I have Windows 7 (64bit) and for a while now, when I'm playing Solitaire and click on the Deck to draw a card, sometimes the Solitaire window will flash and in the taskbar, the Solitaire icon moves/shifts to the right briefly. If I click on the deck a second or third time, it'll be just fine. I've also seen the same issue when playing Chess.

I thought it might be an issue with the window getting/loosing focus but I'm not sure what or where to check...any ideas?

I found that I originally used the 32bit version of Windows 7 Manager and when I installed the 64bit verison and ran the Reapir Center again, it fixed the issue.

Glad it's now working - I'll mark this thread as solved
