possible, but i havent tested the new version of igmon inside the car yet. You can kill igmon and see if that fixes it. When you open ig inside RR can you check what port its using. Since the file menu is missing, and if you have a physical keyboard you can push Alt+F and itll bring up the file menu.
definately a first time ive heard this happen. Try to disable RR from opening the com port just to rule out things.
