Can't setup the Window Background Color

[Csanyi Pal]

Hi,

I'm a Beginner with Project Center, and in Obj-C Programming,
but I like the GNUStep.

I try to make a symple project with symple GUI.

I try to setup the Background Color of the Window in NSWindow Inspector
and when I click in the Background Color Box there I can't to change
the Color. Just show up two small green square and I can't to do with these
anything.

I try to setup the Background color and the Text color of a label but
without success. It's the same problem as abowe.

What is the problem?

My system is Debian GNU/Linux Lenny, and GNU Step was installed
with aptitude.

I have followed the Instructions here:
http://www.gnustep.org/resources/documentation/User/GNUstep/gnustep-howto_toc.html#SEC_Contents 


Any advice will be appreciated!
