For some reason I get graphical glitches in 11.02, and I also can't seem to import projects as modules anymore after a while. I have no idea what's going on but it's unworkable.
So for clarity I'll explain what I did.
I've got 12 multi-module maven projects that need to be open in IntelliJ at the same time. The main project is the one I open first, the others are kind of sattelite applications. I open them as new module. I've been able to open 10 projects like that, but after that not a single project gets imported when I do the same action (new module - external model - maven module). I first thought it was some kind of limit so I removed one module and then tried to reimport it, which didn't work anymore.
I decided to try the new early access version 114.145 but it doesn't even start up. It gives me the import settings dialog with evaluation/license option and that's it. After that it's a java process in sleep mode that doesn't do anything.
This is on Ubuntu 11.04 with Gnome 2.x.
