I'm having an issue where the entire application freezes when I resize the application window. It has something to do with running on a multiple monitors system (extending the desktop mode). I'm running Windows XP Pro SP3 with latest updates and have a 3-monitor setup. After some tests on reproducing the problem, I've come to the conclusion that whatever monitor the app starts up in, will resize just fine; however, if you move it to another monitor and then try to resize, it will freeze up. At this point, I have to use the task manager to end the ganttproject processes. The only way I can move it to another monitor without any problems is to horizontally resize it across to the other monitor, then from the opposite side, drag it until it's on the other monitor as well.
To reproduce (multi-monitor setup required):
1. Open the application.
2. Move the application over to another monitor.
3. Resize it. You'll notice that it freezes on you. In some rare cases, it will not freeze, but rather it will not refresh the application screen.
