Crash when QuickInfo should appear

[knappmk]

Hi there,

my "Orcale VM VirtualBox" doesn't work properly. When I start any virtual machine, everything works fine.
When I let my mouse stay on one of the elements in the bottom bar (s. picture ), so the QuickInfo should normally appear, VirtualBox crashes with the error message: ( - german screenshot)

The instruction at 0x00000000 referenced memory 0x00000000. The
write operation could not be performed in the memory.

Click "OK" to exit the program.
Click "Cancel" to debug the program.

When clicking on "Cancel" a window opens whichs says: ( - german screenshot)

Unhandled Win32-exception at VirtualBox.exe [2540].

Maybe the number 2540 reference to the line number where the exceptection isn't catched.

There are more detailed information about the error in the file ''VBox.log'':

ERROR [COM]: aRC=VBOX_E_IPRT_ERROR (0x80bb0005) aIID={480b372c-c0b5-4c23-9bd7-dcbb85b1594c} aComponent={Display} aText={Could not take a screenshot (VERR_TRY_AGAIN)}, preserve=false

My Windows 7 Version (x64) is up-to-date and I already disabled my anti virus program (What not really make sense, because a unhandled exception isn't triggered by am anti virus program).

This Error also appears on my other Windows 7 (x64) computer with different system settings and programs.

I hope you can help me and fix this problem. Please contact me if you need further information about my system.

Sincerely yours,
Mario Knapp

Please reopen if still relevant with a recent VirtualBox release.
