Thanks John. Downloading now. To be fair. I did one flight in the Dc-6 and one in the MD-11 (Yes, I'm Douglas at heart 😉 ) and I got no crashes. Will test this out tomorrow on my next bout.

It is actually quite difficult to crash the sim with this bug. The problem was that when certain events are received (i.e. an lvar update), the code wasn't exiting that code block for that specific request and was continuing to process the same data as another event. The behavior (i,e. a crash or something else) after it exits what the event that is processed then would depend on what was in the memory addresses being referenced - in 95% of the cases, this would be rubbish/unintelligible and the additional event processed would not do anything, but if this additional event was processed, meaning that certain data read in the event had certain values that were recognised by this subsequent block of code that processed events, then this could result in either an additional non-requested event happening, or more likely a CTD as the event would be trying to access data in memory addresses not available or allocated. Basically, it only happens occasionally and is very difficult to reproduce, but it was certainly a bug and the one that I think has been causing this issue.

Of course, if you still get an issue with this version I will look into it again, but hopefully this updated WASM will fix this. I will probably release this in aa week or so anyway, as it certainly fixes a potential issue.

Well,

I tried a flight today. But the MD-11 has its own WASM crash issues. Anyways, in the 3 hours a had it in SIM I had 0 issues. Including the presets I made. They all worked. Subsequent sim session with circuits flown all as well was good. Hopefully this one can be marked fixed 😉
