Hi Alex,

Thanks a lot, nice patch. I have committed it with one small fix.

That was not a good idea, since at the end we call
	$b->configure(...)
to change the text to "Finished", and with that $b is undefined (the return
value of focus()!)

Did the final button *actually* change from "Cancel" to "Finish" and there
has not been any warning on the cmd line with the perltk installer? I would
be surprised.

Anyway, with my fix (adding above a $b->focus(); instaead of attaching the
->focus()) it works now.

Thanks a lot!!!

Best wishes

Norbert
