I am usng a VM with windows xp. Parallels sets the screen at a particular size that's a little too small. I can easily switch to full screen view, but I'd rather just change the size of the screen used by windows xp, so I can see some of the stuff going on in my mac programs at the same time. The xp virtual machine screen does not have the little expandable corner in the bottom right. Is there any way of changing screen size without having to go to full screen mode? Thanks.
