Photoshop CS3 Cursor Disappears
 

I have 1.5b6 installed on 10.5.8 using the Kensington Display Adaptor with ViewSonic VP912s and a 2008 MacBook. When I open a photo on P/S and try to put the cursor over the image area it disappears (this is true for either screen). If I unplug the adaptor the cursor comes back and plugging the adaptor back in makes it disappear again.

Thanks,
