in thread Perl/Tk window contents disappear when obscured then revealed

Hi thundergnat, thanks for your reply. I am indeed (and unfortunately) trying to do this on Windows. Invoking the external program with 'start' seems to mean that Perl doesn't wait for it. I guess this is equivalent to a background command in a Linux shell. The problem is that I need the Perl script to wait for the external command: the user uses that command to scan a document, then the Perl script needs to go on and handle the scanned file. So I cannot see that 'start' helps.

[karlgoethebier]: no typo
[marioroy]: At the Fransiscan monastery, got stuck up high in a tree from pruning and the chainsaw with large branch fell and broke the latter, but not me fortunately. Was stuck there for a while until a firetruck came by.
[Corion]: marioroy: So you live dangerously ...
[Lady_Aleena]: s/latter/ladder/; # ? marioroy
[karlgoethebier]: marioroy: Praise the Lord
[marioroy]: Well, that's why there must be angels around, invisible or not.
[marioroy]: Lady_Aleena yes, ladder.
[marioroy]: Corion, no not intentionally. not at all.
[Lady_Aleena]: /ne tries to decide whther or not to take a hammer to hubby's alarm clock.
