A little more information is needed here. Does the menu itself appear,
but this item remains disabled (ie, does this menu appear in the MBAR
resource)? Have you put a stop in MyApp->updatemenus to see that the
line is executed? Maybe the document does not appear in the chain of
command. Or perhaps something earlier in the chain (eg a pane->updatemenus
) does not call inherited? A little more info and we'll track it down.

I know how you feel, I am having great problems with bugs that make no
sense now that I am using TCL 1.1.2, which I didn't have with the first
version.
