Stardock Groupy crash

What process crashes?

Bar from Groupy stays visible even when you close window.

That doesn't sound like anything has crashed.

What app / window was the bar for so we can try to reproduce here?

You can not remove Groupy bar without restart. Bluray is connected to usb hub. Bluray data media is burned with windows built in. Windows explorer when browsing folders on bluray data media then closing it. Hope that this is not only my problem.
