PD8 DOES NOT FIX this problem. Do not buy it expecting it to. I had the problem sporadicly under PD7, but in PD8 its constant. I did receive confirmation from support last night that this is a known issue, and they referred my to this: http://kb.parallels.com/en/114472 That is very consistent with my issues. I can also say that upgrading Mountain Lion does not help. It looks like we have no choice but to hang tight and go back to full screen mode.
