error message: windows not shut down properly In starting Parallels on my iMac desktop, OS 10.6.5, I always get an error message that Windows 7 was not shut down properly and asks to start it. What am I doing or not doing to get this error message? The problem is easily fixed by clicking on restart Windows naturally (not sure this is the right word) but I just as soon not have to go through that step. So what do I do to "properly" shut down Windows when I quite Parallels?
