The installer for 1.3.1 then went wrong, giving the error message:
"C:\Users\{myusername}\AppData\Local\Programs\OpenWebStart\openwebstart.jar Could not create this file. Shall I try again?"
I clicked "Yes" to try again, and got the same message again.
I guessed that this was because the JNLP app was open, and openwebstart.jar was in use by that, so I closed the JNLP app, and then clicked "Yes" again, and it worked.
It looks like the way OpenWebStart updates itself at the same time as opening a JNLP app is potentially a problem, because OpenWebStart can't overwrite its files that are already in use by the JNLP app.
I'm letting you know this not because I'm stuck, rather because it looks like something that will cause issues for other users (especially less technical users) when OpenWebStart updates itself in future.
Thank you for all your work on this excellent software
