My Garageband 09 track info pane is not refreshing

I've recently opened some imported projects on my Garageband '09 and for a little while my track info pane updates as expected, but shortly after starting to work on the project it stops displaying Real Instrument and Master Track adjustable settings and windows. I can hover over where they are supposed to be and click to get them to pop up, but I can't see what's there, if they are on or off, etc.

Does anyone know why this is happening and how to get it to refresh normally? I have never had this issue in the past working with other files from the same batch.

Running a 09 macbook pro 13" with 10.8.2, using an M-Audio iControl. 8GB ram, at least 5 free during the run.

Thanks,
