Hi reasonablekeith,

Yes, it's because you're not doing what you think you're doing with:

$check_switch_i->bind('<Button-1>', \&button_run('now'));

If you run perl -MO=Deparse on that, it'll show you:

$check_switch_i->bind('<Button-1>', \(&button_run('now')));

Which means that you're calling bind with a reference to the results of a call to the subroutine button_run.

What you want, instead (if you're going to use that style of notation), is the anonymous list syntax:

$check_switch_i->bind('<Button-1>', [ \&button_run, 'now' ]);

s''(q.S:$/9=(T1';s;(..)(..);$..=substr+crypt($1,$2),2,3;eg;print$..$/
