Top stuff Kostya/Dianne. Thank you for the feedback. I think before I look into anything else, I should do this first to get rid of the thousands of micro-allocations that take place there.
UI elements are drawn about 20 times per second and although I cache values that don't change, a lot of the values do change quite frequently. I'll report back if I'm still having issues after I do this. Thanx again, kk.
