Working on desktop with any app, it jumps to taskbar within 10-15 seconds, it is under the icon of Firefox. Clicking on the icon of Firefox on the taskbar reinstates the program on the desktop but the same transfer happens in the next 15-20 seconds to the taskbar again and again. Same with local, like a wordprocessor or with an Internet connection. Windows 7 Pro sp1. Sony VCP216FX 2 Ghz, 6 Gb mem. To type and send this message the same problem happened 8 times! Note: same with Firefox or Internet Explorer.
