My screensaver shows in Parallels window, but Parallels won't "wake up" when I put my mouse in the Parallels window. My mouse will disappear when I click on the Parallels window...I can get it back using the CTRL+option keys. I can also quit Parallels using command Q. How do I get it to "wake up" without quitting and restarting? Thanks. I'm using build 4.0.3844. I have a 2.66 GHz Quad-Core Mac Pro with 8 GB RAM.
