Minimizing Edius (4.51c) works immediately as any windows program should do.
Reactivating Edius takes minutes. It uses a small portion of the CPU while the Windows taksmanager says it is not responding, but finally it is on top again, but frosen.
Is this a known issue? I've seen a minimize/maximize issue, but it was related to user accounts. I just did a simple minimize and immediately tried to maximize again.

If the solution is difficult to find, it is maybe easier to disable the minimize button as a temporary solution.
