I'm having a strange issue with IR. The in-flight window for part manipulation doesn't show up. I also don't get the option to show it's button on the tool bar. In VAB/SPH I have all the parts and I get the assignment window when I place parts. Assignments from the IR window or the assignment tab do not work while in flight. I've deleted and reinstalled both IR and toolbar and it has had no effect. Is there a key I need to press?
