Why ?

I see. So if there is nothing to compile, it does not rebuild the .icb. 
Seems logical.

OK.

I know Bill, I've no problem admitting I was wrong about this build time, 
this looks as it has nothing to do with the new method (msdev) compared to 
the old one (nmake). At least on your computer :) It's just that it's a bit 
annoying, and I'd like to solve the problem. If I don't, I will find a way 
to output nmakefiles based on dsp files, and we will all be happy.
