The thunderbird profile is stored on the users home share.  This still seems
like a SMB2 problem rather than a UID/GID problem since samba 3.6 works fine
and thunderbird doesn't try and download every message again as soon as "max
protocol = smb2" is removed from smb.conf.  Wouldn't a UID problem remain
regardless of what the max protocol setting was?

> I think you're right about many more programs being affected than just
browsers.  Notepad and thunderbird both seem to have serious problems and
not just with large files.  I was unable to open a very small html file with
notepad and couldn't save my thunderbird preferences so long as smb2 was

Have you opened a bug regarding any of your issues (specifically not being
able to save files and them showing up in the samba recycle bin)?
