It seems like the IconX and DesktopX program isn't very happy coexisting with the RazerHid (RazerHidUsb) mouseextension/driver. This is the driver(extension) for Razer DiamondBack Chameleon mouse.. Same thing on occation with CTHelper, what that program does I don't know, but..
The program sometimes locks up the taskbar and mostly everything else, or just throws the big blue screen.
When I terminate the RazerHid then the taskbar functions as normal again.. This occurs only when those programs AND the RazerHid are running..
