I am having problems opening files on the Windows hard drive when Parallels is open. I can open file from the Mac side in Windows, but not the other way around. If i drag a file from the Windows folder to the Mac desktop i can open them, but when i drag it back it says it is an invalid file format. Parallels support has tried to help but not come up with a solution yet. Is anyone else having an issue or is it just me. thanks for your input. ACB
