Thunderbird editor

[D Canfield <canfield uindy edu>]

I'm having a lot of trouble with the thunderbird 1.5 editor.  Cursor 
movement bounces around somewhat unexpectedly and it's crashed on me 
several times when doing cuts and pastes (even a simple backspace did it 
once).  I've never had a mozilla product be this unstable.   Am I the 
only one experiencing this?  If not, do we know it it's a problem with 
the 1.5 branch, or something that's been introduced in the FC5 
environment?  I'd strongly advocate rolling back to 1.0.x if nothing can 
be done to stabilize this.

Thanks
DC
