When I want to test a new screenres. (or any res.) then the testscreen crashes my Amiga when I click on "OK" or "Cancel".
This is on an A4KD(SB11), CSPPC and CVPPC with OS3.9(BB2). Tested both CGX 4.2 'pre11' update and V4.3beta RC5 update. Same problem on both and I can“t use Snoopdos for this, because it crashes before I get a picture on the scandoubler mounted monitor again.
The funny thing is that my friends A4KD with same config works with no problem.
