I have recently been adding some of the great add on freeware from this site and things have been working out great. With out warning all off my 2D main panels went missing and FSX seems to be stuck looking for them (the hourglass symbol appears and is a shaky shadow behind the arrow). I have removed everything installed after the problem appeared but no luck. Everything else works but the frame rate has seemed to fall due to the computer trying to look for something. I suspect I have destroyed some kind of configuration link for the 2D panel. I have checked it with default and add on aircraft including some of my payware planes and the same thing happens. It works fine if I can get to and aircraft without the 2D panel up and as long as I don't call it up it is fine, Once it is call upon it won't let go of it. It happened briefly a few days ago but disappeared.
