I just looked there, and I found what is causing it, but I still don't know why... It's the ShowInTaskbar property thats causing this to happen. What puzzles me the most is probably that the property is only changed once, but it triggers the DataBindingComplete event 7 times. I have commented out that line until I have some free time figure out what exactly is casuing it, for now people are just going to have to live with the application in their system tray. Thanks for the help mike.
