So I got on to tonight and before doing anything I updated to the latest version of Xlights.
So went edit some old sequences and I seem to be having a problem. I delete the old effect (or click on it) and change the settings, but when I try to play it the old one is still there. If I click on the space in the timeline the old effect is still there.
I thought maybe there was something wrong with my old sequence so I created a brand new one, filled it with random effects, and when I went to delete the ones I didn't like, some of them deleted and I could replace them, but others refused to be deleted, new effects weren't filled in and when I click on the space in the timeline they still there. The very first effect in particular seems impossible to delete and/or change. But it isn't just the first one, others have the same problem, but not all of them do.
