Thanks, that was the clue I needed. I looked at the changes from 221 to 224, and one change was the sound action on button press. I also noticed that you can clear the sound path by clicking the word "Sound" to the left. So I cleared sounds in the 224 version, and that fixed the fakepath. I then found I can reproduce the issue by selecting a Toggle button, On image, Off image, then a bad sound file, then changing the ON or OFF image. Seems fine until you go back to change an image. And yes, the log file is showing an unhandled exception, although I couldn't find the sound file mentioned and it is hard to follow for me.Please try version 221 or older which uses an older version of the barraider tools
Also please check the log file in the plugin directory for errors
BTW, The App never seemed to crash, as I could still assign other ED actions to other buttons.
Thanks for your help. And this App is awesome!
TLDR: Bad sound file caused issue.
