Does anyone know what would be causing this problem? It lasted about 5 minutes before reverting to normal. I've shown the problem panel and the normal panel. It's an old model (Bill Lyons' Waco) - could this be a clue?Thanks in advanceFrog

I've flown the WACO dozens of times, and never saw that problem, or had any other problems. Perhaps you had a bit of corruption during the D/L. Do a delete, and try a new zip file.Part of the secret of success in life is to eat what you like -M.Twain
