Upload from Vista

Hello.
When I try to upload from Vista, I have some problems that I never had before on XP and on version 2 of SmartFTP.
1) Sometimes the "order by date" column is not listing any date at all.
2) When I try to transfer a big amount of folders from my local to the server it says "Merge", "Don't Merge", "Copy but keep both folders", and "Use Automatic Rules". I don't see the option "Overwrite" anymore.

Thank you
