I am running P10 on Mavericks, two monitor set up. My Windows 7 VM is homed on the external monitor. I keep all the other VM's and applications on the Mac's main screen (iMac). Since upgrading from Parallels 9 to 10 (no other changes), I have to extra blank (gray) workspaces on my main display. The icons show they are related to the Windows 7 (the others are win 8 and centos). They appear first (left side) in the list when I bring up new applications full screen. I use mail.app full screen and the Mac knows to start it up in that status. I use Firefox for mac full screen. The mac does not remember the status and I need to maximize it after starting. These extra workspaces get in the way until I manually shift them off to the right end of the selection. Is there a setting that will get rid of them? Another annoying thing that is not new: maximizing or starting max apps on my main display will usually cause my W7 to shift away on the extra monitor. It then shows the Mac desktop on that display. I never use that desktop, so I have to switch back to that side and flip the W7 back into place. It really should stick the way I set it. Don't you think so? Thanks Chuck Sheehan
