About every 5th character I type, regardless of application (be it Twhirl, Firefox, MS Word, CFStudio..) the window I’m in loses focus. This means I have to click back into the window that I’m trying to type. Terribly annoying but I can deal with it because I have to be on my code today instead of on troubleshooting. I’ll run some antispyware checkers in the background while I work. This is terribly frustrating.
Update: This computer has an ethernet card and a wireless networking card. I’m using the ethernet so the wireless is unnecessary but the wireless connection manager kept polling for available networks and that was stealing the focus from the other applications. Disabling the wireless networking connection did the trick.
