Thanks Michael. I am using the CVS-version (dated early febraury) of Emacs. 
I removed the lines I added to my .bashrc and added what you showed to my 
.emacs. Now my bash shell inside emacs looks nice (and in color), but it's 
not perfect. Here it is:

]0;c:/cygwin/home/mikael/coding/Win32/show_styles/src
mikael@mindcooler c:/cygwin/home/mikael/coding/Win32/show_styles/src
$

The first line doesn't look so good and it's basically repeating what's in 
the second line (the path).

How do I make it perfect?
