Mopar1973Man said:What version of VirtualBox are you running (4.3.10)?
Did you try the latest extension pack of VirtualBox?

Yes and yes. I'm not too concerned as 1024x768 is large enough for my needs, but I will figure it out eventually. I didn't have the problem with VMWare and other OSes get access to all of the available resolutions.
