t_Co=8 by default here.

infocmp output shows *colors#8* too, both inside and outside SCREEN.

I will try that, thanks.

Not exactly. I'm sorry that I made a description leading to 
misunderstanding.

There are two remote servers running redhat 9 and debian sarge 
respectively. They have nothing to do with each other actually. I am 
using a windows terminal and login the servers with putty in two 
seperate sessions. Then, I start SCREEN, find that vim in redhat goes 
wrong while in debian it appears right. That's the matter.

I ensured the term options of two sessions(for debian and redhat) in 
putty are exactly the same. So putty can be excluded from our 
discussion, I think.

Then, SCREEN and vim, which one is the cause of the problem really makes 
me puzzled.

The following facts are on the server running redhat 9, the problematic 
one. Colorization of vim works well outside of SCREEN but failed inside. 
So it is likely the SCREEN's problem. But, on the other hand, other 
programs such like ls --color and emacs shows up colorization correctly 
in SCREEN. So it seems the matter of vim. I'm completely confused. :-(

The terminal settings in linux are too complicated for me to master. So 
I post it here for help. Thanks for all giving suggestions. :-)
