Comment 46 for bug 745960

Hi Chad,

this issue has been reported on several machines ranging from Mac thru
x86/x64 VMs to x86/x64 physical machines. I experienced it on a
Samsung netbook and different VMs Virtual Box on two different hosts.
On both hosts inside the VMs, this issue doesn't occur any more.
Regarding the netbook - I simply don't have a disc image to restore
its current state, else I would already have tested it.

Could you take the time and verify the bug is fixed on your Mac, then? Thanks!
