Oh, that reminds me: one thing "Text Editor" does that normal 
obj and msg boxes don't is start a new line after a carriage return. 
In a msg box you hit <enter>, then you have to wait until you type 
another character to see you're on a new line.  If the "Text 
Editor" is going away, that aspect of msg boxes should be 
fixed.

I think this is unrelated to the fact that carriage returns aren't 
saved with the patch; if you're entering lots of messages followed by 
semicolons, you still need to hit <enter> to get to the next line, and 
that's where the quirky behavior comes in.
