Dolgubon, thanks so much! I see that now, thank you for walking me through it! I use your addons all the time in eso, they're super handy and are also a lot of help as far as code goes to get me started.
merlight, oh yes I ran across that post in my search earlier. I really appreciate that and I should definitely look into OnRectChanged, OnRectWidth/HeightChanged. That might make it easier to handle.
But it's really good to know that there are multiple ways to handle the resize, I'll try different ones and see which one I want to go with in the end that looks/feels smoother. Really appreciate all the help!
