The 3 main extern's in my list are:

CBot - The main controller for the application handling the 3rd party SDK
CAwAvatars - The collection of the avatar objects, and the searching
functions (PS: The average count of items in it is usually below 40)
CZoneManager - A large interface for a geographical area defenitions,
polygons etc.

I have no idea why it is compiling so slow then anyway...

EclipseEvolution - 0 error(s), 1 warning(s)

---------------------- Done ----------------------
Build: 1 succeeded, 0 failed, 0 skipped

Execution Time: 1 minute 42 seconds, of that 8 seconds was creating the PCH,
a 1.8Ghz P4 with 3/4 of a GB of RAM. Total Lines: Approx 26,000.

The app is a total solution anyway, its never meant to have bits and bobs
taken from it as its all so intercombined.
