Supreme Council

I'm guessing it's the call to GetVisualInfo() with an uninitialised pointer. You dont assign "scr" to a valid screen pointer until afterwards.

Thats not it, src is set before GetVisualInfo(), read the code again.

if I replace

next = CreateGadget(SCROLLER_KIND, next, &ng, ...

whit

next = CreateGadget(BUTTON_KIND, next, &ng,TAG_DONE);

Then every thing works.

Quite a regular

That's not the best way to reply when someone offers help. He's unlikely to bother again.

You didn't say where it crashed. That might help.

Just can't stay away

GACT_IMMEDIATE, TRUE,
GACT_RELVERIFY, TRUE,

This part should be:
GA_Immediate, TRUE,
GA_RelVerify, TRUE,

GA_Immediate and GA_RelVerify are tags, GACT_IMMEDIATE and GACT_RELVERIFY are flags used for the Activation field of struct Gadget.

Excuse me if I sounded rude, not my intention.
