I'm using the most recent version, downloaded it yesterday.
I just thought about something. You guys think this issue could be related to custom plugins/behaviors? I'm using SpriteFont and another plugin that I can't remember the name right now (I'm not at home right now, so I can't open C2 to see the other name).
Yup, could be a broken plugin or version incompatability
Try uninstalling and then do a clean C2 install, latest version, and create a new project
