"VM Aborted" when VM window covered by other windows

I'm running Oracle VM VirtualBox 5.0.10r104061, a Linux VM on a Windows 7 host.

From time to time I run into a situation where the VM disappears and is listed as Aborted in VirtualBox. The triggering event seems to be that the VM window gets covered by another window. It might go for a month without it happening, and then it might start happening very often (which is the case right now).

The last lines in VBoxHardening look like this when it happens:

2af0.2194: supR3HardNtChildWaitFor[2]: Quitting: ExitCode=0xc0000374 (rcNtWait=0x0, rcNt1=0x0, rcNt2=0x103, rcNt3=0x103, 157852 ms, the end);
27ec.1b8c: supR3HardNtChildWaitFor[1]: Quitting: ExitCode=0xc0000374 (rcNtWait=0x0, rcNt1=0x0, rcNt2=0x103, rcNt3=0x103, 158999 ms, the end);

Can somebody help me with this?

Well the error 0xc0000374 in the exit code should be also at your Windows Event Viewer at the time of the crash to see what more you can find out. From a quick search it means a "Heap Corruption Exception" and a couple of articles that might or might not help you, from that same quick search:

I'd be looking for any theme hacks installed on the host, i.e. those that prettify window frames etc. This sounds like the sort of crash that might happen when VirtualBox hardening tosses that out.

Update: I upgraded VirtualBox from version 5.0.10r104061 to version 5.0.30r112061, and I haven't seen the problem since.

Not 100% sure it's gone forever, but I sure hope so.
