I'm getting a very strange error when I try to launch SSMS from my taskbar. It seems to open in normal speed, but responds to any input with just a beep. CPU usage is 0% in Task Manager, and there is no [not responding] message.
It doesn't respond to a right-click & close all windows command from the taskbar, but "End Task" from task Manager does kill it.
When I launch from the command line and specify the server using the -S switch & use Windows Auth using -E it runs fine.
