I am not able to get a Tk button to auto-repeat on hold-down.
Using activestate 5.8.4

These are the bare-bones of my latest of many different attempts :

$myBut=$dateFrameA->Button(-text=>"- -",
  -width=>2, -height=>1)
 ->pack();

$myBut->bind('<ButtonPress-1>'=>sub
 {
  # button callback  
 });

$myBut->configure( -repeatinterval=>'100',
-repeatdelay=>'100');

Any thoughts would be appreciated

Now why do I know that your questions are always going to be really good ones?  

I'm away at present to don't have a variety of systems to try this out on - but that's what I *would* do if around ... have you tried this under Linux, for example?  Knowing if it's OS / release dependend won't solve the problem but it may give you some clues ...

((Having written that, I looked further at your code and wonder if  ButtonPress is always going to give you a single event as it's the putting-button-down action, and if Button is the event that will be effected by repeat interval and repeat delays.   I may be talking through my hat here ...))
