Ok I tested now.
Running in Amikit XE on Amiga OS 3.2 the screen flash, newmode comes up and allows me to select screenmode, then it just freeze and crash.
Tested on pure and clean Amiga OS 3.2, the system tells me that stack size is low, so I increase it, and then it works fine.
I go back to Amikit, same behavoir as before, except that this time it only freeze (no crash).
Update: I was a litle triggerhappy... i doesnt work fine in os3.2. But I can start it and work in it for a while and then i freeze. In amikit, it will not open, it either crash or freeze before it is opened.
