I have a problem with Yam 2.3p1.  Every time I delete a base64-encoded file, the window I read freezes.  After I click on another email to open, it guru's my system.  I have also seen some garbage characters at the end of the subject and end of the body text.  Anyone have the same problem?  Is there a fix to this?   :-? 
I'm using my A4000T 060, OS 3.9/bb1 installed
