[R-SIG-Mac] NSLayoutManager Exception

I repeatedly come across this problem on my machine (iMac G5, 1GB  
memory, Mac OS X 10.4.9), R 2.5.0, RGUI 1.10 build 4308:

When editing a script in the editor, after hitting the "Enter" key  
the editor does not respond to any changes made to the script.  
Anything typed in is still in the script, but the screen is not  
updated any more, so one can't see what one types. Minimising and re- 
maximising the window doesn't help either - that's how I worked  
around that bug in an earlier version of the GUI.

The main window reports the following:

2007-05-04 13:28:20.107 R[3841] Exception raised during posting of  
notification.  Ignored.  exception: -[NSLayoutManager  
_fillGlyphHoleAtIndex:desiredNumberOfCharacters:] *** attempted glyph  
generation while textStorage is editing.  It is not valid to cause  
the layoutManager to do glyph generation while the textStorage is  
editing (ie the textStorage has been sent a beginEditing message  
without a matching endEditing.)

Hope this is of any use,
