Mine Gnome (2.4.0) and Emacs 21.3.50.5 (a bit old, was it late June or  
July, I don't recall) doesn't have this problem.

xterm does show a different scrollbar, because it's not using the same  
toolkit (Gtk+), but Galeon 1.3.7, Emacs, and all the other apps show  
scroll bars as set in my theme.

For me, blue appeared as background of the arrow buttons when I pressed  
and held arrow buttons.

This seems to be a theme issue to me. I'll try to find out later if  
there's a Gtk+ theme which has a greater contrast between the thumb and  
the entire bar (you may also try looking at art.gnome.org in Gtk+  
section, if you find some spare time)

Perhaps I'd need to check with a more recent Emacs CVS version, since  
for me, the entire bar and thumb (ok, I'm not really sure what is  
"thumb" in this context, but I hope I got it right ;-) are yellow.

For a start, I'm certain that there're no such problems in 21.3.50.5  
from 2003-06-30. I've updated Emacs from CVS, and I might try it again  
with it. If it turns out to work like you describe, the bug must have  
been introduced somewhere in between.

As a sidenote, I expect most of the people using Gtk+ toolkit to use  
the default desktop theme, because that's what they chose for other  
apps too.
