Balsa 2.5.2 "Failure to sync mailbox xxxx"

[Fred Smith <fredex fcshome stoneham ma us>]

Hi all!

I've just compiled Balsa 2.5.2, which went without significant issue.

but when I open my main mailbox, clicking on some messages elicits a
warning box pop up saying "Failed to sync mailbox xxx".

I see that message could originate in any of a bazillion (more or less)
places in the program, but haven't yet figured out which one, nor 
know what it actually is trying to tell me. what problem causes this?

anyone know a magic incantation to solve it?

thanks!
