Guest OS goes blank and then reboots when opening mounted shared folder.

[Tom Rogers]

Hi, when i set up and then mount a folder share, my guest os seems to fail. Upon opening the mapped drive the system stalls for a second or two and then goes blank. The system then restarts itself. It is not shutting down, simply going completely blank instantly. My host OS is OS X Lion and my guest OS is Windows 7 Professional. Full details of everything tried so far can be seen on the forum thread: ​https://forums.virtualbox.org/viewtopic.php?f=2&t=45264

I have guest additions installed as well as the extension pack. The problem is continuing to persist and the forums have not solved it. I am attaching my log file. Please help.
