Known Problems:

********************************************************************************************************
Animation Path Bug:
There is a bug with animation paths that screws the path up if two key frame 
points are the same 

Work Around:
Make sure you move the camera and target on every key.

The entire way animations are produced will be changed in future versions 
this problem will be eliminated then.
********************************************************************************************************
Render appears to lock on rendering the sea:

Some times the progress bar may appear to have stopped whilst rendering the 
sea , this occurs because the sea is rendered as two triangles i.e. the 
progress bar has only two segments and is just taking a long time to render. 
Note this is also a problem when trying to multitask, windows will lock 
whilst the sea is rendered !!!!!!!
********************************************************************************************************
Some times when using a 256 colour driver the palette screws up

This can happen for instance when a paint package is used or when the colour 
map editor is used or sometimes the colours are wrong on startup.

Work Around:

The palette will be restored after the next render.
