So I'm running netbeans 7.0-1 using Arch Linux. I'm running xming for my x-server.
What's going on is, when I use netbeans' Desktop Applications, it starts with two menus: File and Help. Whenever I click the drop down menu, the drop down immediately disappears.
I'm not even sure where to start... it seems like a bug. Any ideas?
So as it turns out... I needed to set the enviroment variable AWT_TOOLKIT to "MToolkit"
That seems to have fixed the issue.
