Thanks for your reply. I had to leave and run some "errands" so this reply is tardy.
I want to make sure you understand that I REALLY appreciate what you do and the product that is xLights.
I also am not surprised that conversion from LOR is not the strength of xLights. I had suspected as much. I have forced the issue this year (taken long breaks, gotten coffee, etc) while working with the LOR converted sequences. I suspect that I will move on to new sequences over the next year.
As for FPP Connect taking a long time just to load (I timed it at 3 minutes today when the computer was otherwise idle), I also suspect that somehow just having the LOR converted sequences has slowed EVERYTHING down. I actually had to uninstall it on my second computer because other unrelated things were locking up. Uninstalling xLights solved the response problems on that computer.
Again, thanks for all you do. I'll simply turn the page and move on next year.
