2.41 Unstable with high detail, and vertical exageration, loading projects.

[BenWiseman]

1. On loading projects you get a DLL load followed by a bunch of wxWidgets problems
   
   exception

2. Vertical exaggeration still not working. Trying to set the vertical exaggeration to anything more than 0 with max detail causes the program to crash with code GL_NO_ERROR.
   If my DEM is in .tiff format (.asc seems worse) with <= 2048 terrain resolution, the program will still trow frequent exceptions and will only sometimes work with both high quality and non-zero vertical exaggeration (if I set the project's terrain resolution lower it will throw fewer exceptions, at higher resolutions it either crashes or will not increase the level of detail).

My GPU isn't breaking a sweat (<= 5% load, negligible memory usage) so I'm pretty sure it's not hardware related, maybe a limitation in openGL?
