I am running PD8 build 8.0.18608 with a VM of Windows 8 with Start Menu 8 installed on an iMac running OS X Mavericks version 10.9. After the update to Mavericks, it seems as though I have a sticky key problem. Randomly, it would seem as though a sticky key has been enabled (even though no prompt has notified me of this). What happens is when I start typing, many of the keys start performing actions in the VM like start menu or opening the side menu (win8) or launching OneNote. I went into the shortcuts section of the PD8 preferences and disabled all of the Cmd shortcuts under all of the VMs as well as Application Shortcuts. I even went into system shortcuts and set "send system shortcuts" to "Never." I didn't think this would solve the problem since it governs shortcuts sent back to OS X. But, I am grasping at straws. I have disabled sticky keys in Win8. However, it still occurs. Does anyone have any ideas?
