Re: non-display of assembly

Tom,

Some unexpected error was hit which messed up Insight.  The best first 
stab at debuging this sort of thing is to do:

setenv GDBTK_DEBUG 2

in the shell from which you launch gdb.  Then do whatever you normally do,
keeping an eye on the debugging window.  Errors will show up in an
orangish color.  This might give you a bit of a hint...

BTW, if you forget to set this env. var, you can also go to the
console, & type:

(gdb) tk ManagedWin::open DebugWin

Otherwise, I need a recipe for reproducing your bug before I can be
of much help.
