It could be that there's some connection between your problem and mine, but 
I guess it could also be just coincidence.  In any case, if I work out what 
was wrong, I'll post it here, in case it helps others.

That's certainly possible.  I might see if I can find some Tcl/Tk code to 
try running in that environment.  Again, I don't have any kind of 
administrative access on that system, otherwise I'm sure it would be sorted 
out by now.  It's horrible being "just a user" when you're used to running 
things :-).

Yes, it certainly seems strange to me that the code even works, let alone 
that you need to do it that way.

That would be nice.  I'm going to have a look on RAA and find out who the 
developer of Ruby/Tk is and try approaching them to see if they have any 
ideas.
