Random windows background color

Hi all,
I have a really weird problem. I'm using 4D 2004.7r3 on two intel mac with
the last 10.5 updates. My 4D application draw the window that contain some
array objects uding a very dark grey. This problem afflict all form that
use array, hlists, listboxes. If I delete this objects form the form the
drawing is correct.
The strange is that ALL the windows are affected. Also the explorer window
from the design environment!

I suspect that this is a bug in 4D, and I'm  going to try 2004.5 and other
older release.

Anyone can help?

TIA,
Gianluca
