Dear all,

Thanks for all your time here. It's very much appreciated!

Hans: I do mess with fontdimens a bit, but not enough to cause this  
sort of problem. The global assignments there did catch me at first,  
though. But I wouldn't have expected fontdimen changing to affect the  
space between *letters*...

Well, that's glad to hear :)
Delays for the update aren't any trouble...the bug doesn't stop me  
from doing any work on the package.

Hey, you're right! I *am* using \font more than I need.
That wasn't very clever of me, huh?
One day I'll learn...

Thanks again,
