I have windows 7 professional installed in parallels 5, and if I copy more than 1 file from windows to mac that are already on the mac desktop it asks if I want to skip, or replace. If I choose replace, to replace the files on the mac desktop with the files from the windows machine...parallels gets stuck in "Preparing to copy" with progress bar. It never does the copy. Also, I can't get past the "Preparing to copy" back to the virtual machine. I have to shut down the machine from the parallels icon. Has anyone noticed this problem? What could I do to fix this? Please help
