Well, it almost works. Current CVS just process only the first key,
because popup_activated_flag is 1 only at that moment. After the first key
is processed, popup_deactivate_callback is called (many times) and that
variable is zeroed. And from now on, key in menu are no longer processed.

Good. After:

Menu works, because popup_activated_flag is going to negative numbers very
fast... But I can no longer enter any character in the buffer, because
those keypress events are processed in menu... So I think it is not about
Lesstif knowledge, it is about how Lesstif is used in Emacs. I do not use
Lesstif so perhaps Gerd can help me. Or anyone else?

Yes, this will be the second step. But I;d like to finish this one before
doing additional things.

I think it is very easy. We should use F10, and invent new variable
f10-should-use-tmm (this is only idea to exactly describe its meaning...)
defaulting to nil.
