If your Radeon 9200 or 9250 won't do the per pixel thing here's how you do it.
step 1 uninstall all ati software, catalyst control center, control panel and 5.9 drivers.
step 2 reboot.
step 3 find your original driver disc that came with your card install drivers only (choose custom install) don't install the control panel.
step 4 open windowblinds choose a per pixel skin and your away!.
don't ask me why (no idea) this works for me and master KOL he's got the 9250.
good luck.
