Paul,

I haven't upgraded to 4.2 yet -- it was announced only *days* after I had
acquired and (laboriously) upgraded 4.1 from 3.03 :-(

Sounds to me like 4.2 may have 'upgraded' tcl, tk, and/or blt -- most
likely, it mucked up blt. [ What versions of tcl and tk did you get? ] My
suggestion is to re-compile blt2.1, taking care that the references to tcl
and tk in the config files are correct.

Good luck,
Sven
