Re: Recent drawing optimizations

[Stefan Urbanek]

Hi all,

Can please someone with knowledge of that issue look at it? It is really 
serious.
Most annoying is, that I need to launch gnumail for more than four times to 
finish some longer emails. And i am not talking about emails i have lost in the 
middle of writing/replying :-(

Literally, GNUmail is unusable due to VERY frequent crashes.

Thank you,

Stefan
