I am running Parallels on a Mac (OS X Leopard, 10.5.7) in order to run Windows XP. My employer has fairly restrictive controls on the Windows side. When I logout from Windows XP, to shut down Parallels, I am being prompted for login information for the Mac side (to sync with my home folders). I have not seen this before, in previous versions of Parallels. What is my appropriate response? My Mac login doesn't seem to work...
