Re: [OpenMap Users] Problem minimizing a jinternalframe

Hi John,

I'm wondering if JInternalFrame needs a root pane set somewhere to
minimize to, like a desktop? I know I've done this in the past, but
the icon went to a place on the 'internal desktop' as opposed to the
OS location for icons.

Just out of curiosity, what OS/JDK are you using?
