Client Crash

Win 7 64
gtx980

Steps to reproduce:

1. Open client and firefox.
2. Set client to true fullscreen.
3. alt+tab-out, close firefox, let Windows automatically give focus back to client.
4. alt+tab-out again.

Update:

The same bug (I think) just triggered Program Compatibility Assistant in Windows 7. I.e., it seems to think it is an older program which is not fully compatible with Win7.

Not sure what the significance of this is, or if it is significant at all, but thought I'd add the info just in case.
