Revert back to b39?

Since updating to b40 ( I am still on Sonoma) I have been having some errors when one of my procedures run and has caused Pan to quit unexpectedly numerous times. I would like to go back to b39 but not sure how to do that. Is there a download somewhere to re-install b39? I thought I read where b40 might have issue with dialogs in procedures? I do have some of these in my procedure that seems to create the quit.

Choose Check for Updates … in the Panorama X menu. Then choose b39 from the Versions menu.
(Note: b39 is not recommended for use under Sequoia.)

Well. Thank you. Never knew that was there. Awesome.

Tried this method, but there is no ‘Install’ button. Running b41 and want to go back to b39.

Never mind. Found an older version I could ‘update’ to b39.

For future reference, you first download the version, using the Install menu.

Once it has been downloaded, you will have an Install button.
