Sorry, will make sure to take a screenshot if it happens again. I saved it, exited xLights and restarted and the issue is no longer present.
But, if I were to try and explain better, I have a timing called "Voice - Main" I set a start timing mark and end timing mark and shift-double clicked it and entered a phrase, which was completely visible on my screen. I then right-clicked and said to breakdown phrase at which time the phrase went a tan color, but scrolled right past my end mark off the right side of my screen. The words appeared, but again went way off the screen. To adjust the words to match the song I had to slowly move my mouse until the cursor changed to the right<->left arrows, and I could grab this blank area and adjust knowing it was my first word. Even though the word wasn't there I could right-click that area and tell it to Breakdown word. Then a long pink line showed up, again going off my screen to the right, but I could take that and slowly move my mouse and adjust the phenome's.
So, since it corrected itself after exiting, please ignore this. I'll make sure to grab that screenshot if it happens again. I posted because I noticed changes were made to this process in the Read Me file when I upgraded.
