I've following Problem: Starting and running one copy of EnB works fine. But when I start another copy the 2nd one runs correct but when switching with Alt+Tab to the 1st one the Mouse hangs in the upper left corner and nothing happens. I can switch back to the 2nd one wich still works fine but I cant use the 1st copy. Bur I can hear the sound of both copys and the Taskmanager shows both running without Probs.
