no matter where i use:

Amazingly, what worked in the end was simply adding
-state=> 'disabled'
into the actual $menu->command, hence avoiding the documented
"entryconfigure" method or cget altogether
but if anyone has any patience left could you explain:
my $state = ($count++ & 1) ? 'normal' : 'disabled';

with eliminated
instead of "shaded" entries, but as always anyone who can successfully
explain these mysteries better to me is very welcome to try ;)

okay, this is definitely a Tk or GUI issue, since incorporating a for
real "print" (ie. to STDOUT) statement does come out in proper sequence.
Does anyone know if there is a filehandle other than STDOUT for tk
requests?
The simplest version of the problem:
use IO::Handle;
sub tmptest {
