Mad Dog w/Radeon 7000 looses signal

[Jay Daniels]

I have xfce installed and it works perfectly except for one problem. 
About once a day or so the windows go crazy and/or the monitor either
looses it's signal or the keyboard locks up - usually occurs while using
the mouse to page down. This requires hitting the reset button.

Currently using a ATI Mad Dog w/Radeon chip 7000 dvi32mb version and
RedHat 7.3 w/updates on an AMD 500mhz with 448MB RAM and fairly new Sony
17in monitor 200ES.  Logitech Mouseman 3button ps2 mouse.

The reason for posting this here is because I never had a problem with
this box in Gnome.  Also, when I tried true color at 1024x768 the
problem was a lot more visible and would occur quiet often!  Now I have
it set to 1024x768 @ 16bit color and crashes are a lot less, like once a
day.

Any ideas?

I downloaded and installed the development version thinking it may solve
this problem, but it seems to be still using the old version of xfwm.
How do I get startx or startxfce to use xfwm4?
