Application windows constantly losing focus.

by jshanks24 / February 19, 2008 3:16 AM PST

I am having a new issue with my Vista desktop. Every few seconds to a few minutes my current window will lose focus. No other application gains the focus, Vista just becomes unfocused. The newest addition to my PC is a bluetooth keyboard and mouse. The Microsoft Wireless Entertainment Keyboard 7000 and the Microsoft Wireless Laser Mouse 8000. I believe it is a bluetooth issue, but how do I get it to stop. I generally play games and do chat or web browsing. Mouse clicking is the only thing that isn't really impacted, otherwise the system is currently barely usable.
Thanks in advance.

Caused by other program

I had the same problem with my application windows losing focus every few seconds. I'm running on Vista Business.

Found out the problem - caused by Sony Ericsson's PC Suite v3.2. When the PC Suite is activated (even if minimized into tray-bar), other application windows lose focus every few seconds.

I suspect this may be due to the software searching for my phone via Bluetooth. My phone's Bluetooth connection is usually disabled.

Closing the PC Suite solved the problem for me.

Hope this helps.
