Hi,

Thats one crazy piece of code:

function updatescreen()
for done=1 to 35
if spriteexist(done)=1
sprite done,spritexpos(done),spriteypos(done),frame(done)
else
if sprite exist(done)=1 then delete sprite done
endif
next done
endfunction

1). You need to put a space between sprite and exist on line 3
2). The else part of your if statement won't do anything because at that point sprite exist(done) will *always* equal 0.
3). Change line 4 to: Sprite done,SPRITE X(done),SPRITE Y(done),frame(done)
4). Check that frame(done) returns an existing image.

spriteexist(*) is an array. the problem is that when this runs the screen flashes and exits to windows without warning..
