Hi


hmmm, crashes here too, even without scrolling that much. As there's no 
border removal / resolution changes, I suspect this may be a problem in 
the STE DMA sound emulation, which uses internal hatari's timers too (as 
it happened once in the EPSS demo).
I will try to capture some traces, but this will be difficult as it's not 
easily reproduceable and the demo can run quite a lot before freezing.
