I think I've found an interesting bug, but it has an easy workaround. I upgraded to Mavericks yesterday, and already had PD9 installed. After my Win7 VM idles for a while I can click on the PD icon and it appears my desktop is frozen. However it actually isn't - it is just in the lock screen, but the image just prior to the lock screen is being displayed rather than the lock screen itself. So while it looks like my Win7 vm is frozen (for example, on my Outlook inbox), all I have to do is hit CTRL/ALT/DEL to bring up the login screen. Perhaps this is an idling / CPU optimization issue, but I thought I would mention it as the first few times I thought my VM had crashed.
