Dear Monks,
Perplexity hardly only comes once, so please excuse me posting two questions within so short a time.
I have a new Tk widget, created as a custom widget as described in Mastering Perl Tk. All similar widgets work fine. This one (derived from a dialog) does not show and the application hangs when it is called. A print statement at the end of the Populate method prints fine. I am not sure where to look for reasons why it hangs next.
The script is running Perl 5.8.6 on xp home SP2. One thing I have never noticed before is that usually when perl hangs it takes most of the CPU usage. In this case it troddles at less than 25% while csrss.exe get most of the remaining cpu load. What can cause this?
Thank you for all help.

Cheers,
PerlingTheUK
