I can't imagine running a development tool under MPW without that 
behavior...it's what every compiler, etc, has done under MPW since 
1986.  Since MPW installs itself as a "foreign file system" <it was 
the first, and until CDs the only, one>, it's hard (if possible) to 
know whether output is to a file or a window:  a window IS a file. 
[This is why you don't need to save a script you are working on in a 
window...just execute it from another window and the current contents 
of the window ARE the file.

An alternative would, I suppose, be to write an MPW script which 
responds to your favored error output format in a rational way...that 
would still be harder to use than "Click in the error line, press 
enter".  The script would be run from a menu (or button in the newish 
MPW) and would try to parse the Perl-style error in a useful way.
