Hi,

I recently updated my Pixinsight to the Mac/arm 1.9.4 version. So far so good, except when I am loading FITS files that have previously been processed by subframeselector Ono earlier Pixinsight versions, I get the following error:

Have any of you seen this? Any ideas on how to fix it? Thanks in advance!

Ah, I found this on the pixinsight product forum:

https://pixinsight.com/forum/index.php?threads/errors-while-opening-any-xisf-file.27200/

This is not a bug. These errors are caused by unavoidable breaking changes during the integration of the new V8 JavaScript runtime. The two processes affected by these changes are:

- AutomaticBackgroundExtractor
- SubframeSelector

The breaking changes are due to insurmountable design mistakes in the original versions of these processes. You can ignore these errors when opening an image, as they only affect the stored processing history. If the same errors appear when you load a process icon or project, you'll have to review the affected icons and regenerate them from their respective processes.

I forgot to include this information in yesterday's official announcement. I'll add it as soon as possible.


But a user mentioned the same problem as me (needing to close the modal dialog boxes). Hopefully Pixinsight finds a way around it for users…
