Hi, Patrick and Sundar!
I have had a comparable problem with a Change event in a rich text field.
After a few hours of experimentation and a peek at Aldo's examples and at
some Win32 API documentation, I found that I had to send a 1093 message to
the widget before using the callback, like this:
$RichTextField->SendMessage(1093, 0, 1);
I don't know whether 1093 will work for listboxes, though. Perhaps those
need another "magic number"?.
I would say it IS a bug in win32::gui that the message hasn't been
"pre-sent", so to say.
