Ommmmmm.

Pondering has lead me to write a PerlTk GUI for a process control. Since it not apparent how to add file descriptors to the event manager (as in X), I tried to put the GUI in one thread, and the Msg I/O in another.

Calling the GUI as a subroutine works just fine.

But as a thread, it fails:

......
#gui();   # works
#       below fails 
my $gui_thr = threads->create( \&gui );
my $res1 = $gui_thr->join();
...
sub gui {

# mw contains frames 1,2 and 3 top to bottom
    $mw = MainWindow->new( -background=>"$stock_bg");
    $mw->resizable( 0, 0 );

Correcting the error seems beyond my skill level.
