I am running thunderbird with IMAP and each time I open thunderbird it begins to download all 130K messages. Upgraded to 64 bit doesn't seem to help. Searched my harddrive for .msf files mentioned in other fixes and while I am sure they are there they must be hidden from me. Its just me, one computer - no company or other server setup. Would happily pay for help if there were a number to call to solve this problem
