Is anyone having issues with people you share folders to NOT being able to upload files? I have given two family members full-access and they can't upload. The process gets all the way through "adding" the file, clicking "open", but when they click the "upload" button nothing happens.

They are running Windows7, IE7 with pop-up blocker OFF, XP-Pro. I've cancelled their accounts and resent the authorization email, etc. ... still not working.

Thanks for any help.
