That looks very strange.
Can you reproduce this error, as I can’t.
Does it only happen with a particular track (if yes, please can you send that over to me).

It was not excepted, we are currently live and thankfully it did not close ProppFrexx.
One thing I noticed is that the playlist did not scroll, so had to open new playlist, and seems ok at the moment.

As said, please try to reproduce the error, if that happens only with a particular track within the playlist.
As I can absolutely not reproduce it here.
I have however opened a ticket with my UI vendor, as the error occurred inside their UI library - maybe they can spot anything.

Thanks for opening a ticket.

It was a big panic yesterday when the error appeared on screen in the middle of a live event on DAB around the country. First time in using ProppFrexx in a live show.
I could not check what track was causing the issue as we were live all day doing a road show. The only difference is at the time of the error, we were using the remote app I created to start the song by sending the commands via TCP.

I've checked the track, and works fine as usual. I will run more checks in the week to try and reproduce on the same computer with the app.

Thanks again for your prompt support.
