Johan,
I tested your script with 0.0.665 on Win2k,
Works as you describe, shame about the jumping though.
I used to call Dialog this way, (ignorant of modal I admit) then I read
methods.html in the docs which states,
"note that this function must be called without ANY parameter or
instantiation (eg. don't call it as method of a created object):
Win32::GUI::Dialog(); # correct
$Window->Dialog(); # !!!WRONG!!!
"
Perhaps Mr Calpini , chose to hide this feature because it still had
problems ??
