So give than you have a reproducible case could you do me a huge favour and create an image that reproduces the bug? Please create the image as a doit that saves the image and then continues to runt to the crash. e.g. if the code that provokes the crash is "MyTest crash" evaluate this in a workspace, and then verify when you start-up the resulting snapshot that the image crashes:</div>

Hi Eliot. While trying to make the image for you, I found that if the test is run from the image start, as suggested above, the crash doesn't happen. If I do the same but from a "DoIt" in a workspace, then it happens. So I think that maybe I am becoming some contexts/compiledMethods from the executor (the DoIt) of the test...kind of shooting my own feets. But it is difficult for me to know whether a context or a method or whatever comes from the executor of the test or not....<br>
<br>If you think that even if you have to do a do-it from a workspace it helps, then I am happy to upload an image. Otherwise I will continue investigate what is wrong...<br></div></div></blockquote><div><br></div><div>Just keep fiddling adding other things to run (e.g. open a browser programmatically etc). There's very little chance of debugging this from an expression in a workspace. Even if you give me the expression I will have to spend my time making it reproducible from start-up to have a chance of making sense of the crash. So please, can you keep trying?</div>
<div><br></div><div>Basically the debugging process involves analysing, working back from the crash in subsequent runs. Without a case that reproduces from start-up it is IME very difficult to make sense of.</div><div> </div>
