Just to let you know, had a small epiphany and got it work, finally. The issue I was having previously was that I had placed your macro in my general "app centering macro", that I was triggering on display change. This caused the macro to get stuck as it was waiting for the conflict palette to become visible to be able to adjust its position.
This time around, I simply put it in the palette-triggering macro, instead. Works great. In hindsight it's obvious, but I think my brain was fried at that time and it just didn't strike me.
Once again, thanks for all the help, Chris. I'm sure others will benefit from your work
