has anyone seen this weird problem: a text entry box is open for some app (for example, text entry for this forum using firefox). i enter one letter and the firefox window is immediately no longer the active window. so tapping the keyboard does not enter text. if i mouse click in the text window, i can enter one more letter then the browser is again no longer the active window. it happens with different apps from time to time. if i close the app and re-open, behaviour is usually normal again this is XP pro sp3, a recent fresh install. i have a lot of apps running at different times. i started using online armour firewall, thought that might be the culprit...but i stopped running OA a week ago, and it still happens. i run yadis real-time backup. but the prob can still occur when yadis is not running. because it is intermittent, it's hard to isolate.
