I have CyberVision64 3D and recently I bought a scandoubler. For a few days I had to go AGA 'cause I had a problem with my monitor and I had it for repairing.
When I changed resolutions of wb in AGA it crashed, and now that I have back my monitor and I use p96 I changed to 1024x768 with save from 640x512 and it crashed yellow and then black screen. When I booted I tryed to change to 800x600 and nothing happened but when I tryed to load last saved it crashed again.
When I open apps in different screens nothing happens so it must be a software problem with workbench.
