Balderdash.

We use TBird on all 55+ machines in our office, and regularly deal with 
large attachments - some as large as 50MB...

Of course, there is the *occasional* issue where someone tries to open 
an attachment before the message is finished downloading - this can 
confuse TBird (and probably other clients), and you have to force TBird 
to redownload it again (by deleting the local cache - or by forwarding 
it to yourself as an attachment)...

But this is a USER issue - tell your users not to try to open the 
attachment before TBird is finished downloading it (the status bar is 
finished).
