Script won't reset if displaying progress in SD

I have an applet that uses progress.

If I run it in script debugger, and it displays progress, and then I click the stop button while it’s running, the script stops, but doesn’t fully reset.

The Play button appears, but I’m unable to edit the script. The stop button is deactivated. The Debugging button does not appear.

It’s difficult to get the script to reset. (I have one in a state where I’ll need to force quit.)

There are some things I can do (like find, or open/close inspector panes. There are a few menu options available.

If I close the window I get an alert the script is running and I can “Stop and Close” and sometimes that works, sometimes it hangs. (It’s hung now, I’ll see if I can sample).

I’ve noticed this in a couple applets, but it looks like progress is the only thing they have in common. (I don’t use progress very often).
