Here's a weird one.  I have a deHaviland Beaver float plane designed for FS2000 by Fred Banting.  The engine cranks but will not start while in cockpit view.  The fuel tank selector flips around wildly while the engine is cranking.  It will start in HUD view but stalls when changing from any other view back to forward HUD or when going from HUD to cockpit view.  I've written Fred about it and he has never heard of this before and was unable to replicate it.  We think it may be a conflict with something else.  Anyone have any thoughts before I go ahead and reinstall the game.  I'm not looking forward to putting all the addons back in.
