Hello,
I have window blind 8 installed as well as the Windows 8 start menu, and have put a taskbar on my 2nd monitor.
When window blinds is running, there will be times (not all the time) that the taskbar on the 2nd monitor will keep popping up in flashing. The regular taskbar on primary monitor one that is provided by Windows does not exhibit this behavior.
When I unload window blinds 8 this stops happening.
The programs that I have open are usually just Internet Explorer, Google's chrome, and Dragon NaturallySpeaking 12.5.
