Picasso IV How to boot and get video?

[videofx]

I have a Picasso IV in my 4000T. If I boot from the Install WB 3.1 floppy video from the Picasso IV is fine, When I boot from the Workbench 3.1 floppy my monitor displays out of range and no video. So for testing I have my 1084 monitor connected to the standard 23 pin video connector and video is displayed perfectly. So why can the install disk work and not workbench? I have tried all the different jumper settings on the Picasso IV and no change.

Thanks!

I agree but can I fix it?

Thats the million dollar question. How to reset the flickerfixer settings. When I boot with left shift I get into the Picasso IV but there is nothing to set for my monitor only reset to defaults which has no effect.
