<br>
I have a visualization demo. It runs in a separate process to permit
mouse and keyboard input while it runs:<br>
startChaosAnimation<br>
currentState = #CHAOS ifTrue: [^self].<br>
currentState := #CHAOS.<br>
processSemaphore wait.<br>
BB2ChaosCtx startChaosAnimationOn: data.<br>
processSemaphore signal.<br>
] fork.<br>
<br>
BB2ChaosCtx startChaosAnimationOn: data starts a loop that creates and
removes Morphs interspersed with suitable Delays to get the speed right.<br>
<br>
The process can run for several hours before crashing in various ways.
It sometimes crashes with a primitiveError while redisplaying World. A
simpler stop was an MNU in<br>
MorphicEventDispatcher>>dispatchDefault: anEvent with: aMorph<br>
where aMorph = a PasteUpMorph [world], with fullBounds = nil<br>
<br>
My process is clearly in some unfortunate state when the main process
repaints or handles the mouse. Any ideas how I should make my process
safe?<br>
<br>
Thanks in advance<br>
