Derek,

I just found out that there are already some controls pre-created in 
win32lib. because when i crushed my program and checked the length of 
the window_handle. it had extra -1's. This is due to the internal image 
lists that are made. Derek do you really have to create ImageLists() 
using NewControl() it is a waste of time and laggs win32lib efficiency. 
I don't have win32lib to verify i'm right since i'm at an e- cafe. but 
i'm pretty sure i read this in win32lib some time back!!!
