I have observed this windows happen while downloading from a msn.com account.
TypeError : str is undefined
the downloading is very slow.
In general :
gmail and hotmail accounts don't go well. Seem dowload only a few emails .
By example : today 08.09.2010 download four emails from the date 08.02.2010 .
And I see all emails are not download.
I have multiple filters defined for these accounts.
I suppose I need to reconstruct my profile or try to repair step by step.
What can i do ?
