Sorry, I'm just a bit overwhelmed by feedback in general.

If I wrote that then I didn't word it correctly. I don't know if an 
Apple bug might play a role. In fact, I think it's a MailMate bug 
somehow related to how MailMate updates the window when updating the 
preview. So far, my attempts to debug the issue have not helped much and 
I have not been able to reproduce the problem (with or without 
attachments). I've been postponing looking into it until after I've 
finished some code which should make the update of the preview 
asynchronous. That might not help, but at least it'll rule out the 
problem of preview updating being slow.
