Constant crashes. At my wits end now with PI.

[joelshort]

Hi Juan,
I have this Blink problem as well, going back a few months.  The problem happens exactly as you describe (when I "close all images" in Blink).  I have pasted the error code below.

I would very much like to get the fixed testing version and am happy to test it.

Juan is working on a new Pixinsight executable and I have been one of those testing it for him.  Progress is being made.  There are hundreds of points where this Qt code can cause a problem and Juan is trying to find them.  He has found many already.

Progress so far seems to have repaired most of the preprocessing crashes.  I was getting them every time I used PI but now they seems to have largely gone.  I had one yesterday with the DBE process so it is not solely linked to preprocessing.

Hold on whilst the issues are figured out.  Juan is aware of it.
