I'm having trouble getting your application to run on my windows XP SP3 system.Version 6.1
opening file explorer and clicking on ....GUI.exe, I see opening window of your GUI app for about 3 seconds, it then disappears and file explorer just hangs with a hourglass cursor. Task manager says file explorer is not responding, can't quit file explorer and have to reboot to recover.
Instead of re-booting, open Task Manager and 'End Process' on explorer.exe. Then from within Task Manager do File->New Task and type explorer.exe and hit okay. Should be quicker than re-booting.
