Openpanel does not output anything if "cancel" is selected on the Windows file open dialog. So, no way to tell if user cancelled or is just taking a long time to select the file. Is there another object available to open windows files that would have this functionality? if I wanted to modify the behavior of openpanel, would I have to compile the entire vanilla package? I can't seem to find source for just the openpanel object. It would be great if it would just output a "0" or somehting if cancelled.
