Some Win32::GUI Perl objects contain handles to Win32 (os level) 
structures, which are deallocated once the Perl object is destroyed. That 
might be considered a good thing.

What might be considered a bad thing is that some Win32::GUI controls 
doesn't take the responsibility to keep the reference count for the object 
up so it doesn't get garbage collected and destroyed while in use (if you 
declared it as a lexical variable). So you'll have to do that explicitly by 
e.g. assigning it to the property of another, more persistent object, or to 
a package var that never goes out of scope.
