Most annoying thing for me, the aircraft selection. Firstly it takes ages to load

Sorry, then I understood this the wrong way.

However, the thing on the aircraft selecting and the mouse wheel happened here too. But I got into the habit of clicking once into the screen before scrolling. Maybe it helps.
As said, I think I saw some Avsim posts on a different FSX interface with lots of improvements. Maybe the a/c selecting is one of them, I haven't tried it.  :-[ http://www.codelegend.com/idealflight/
