I figured out part of the problem, but I do not understand it enough to figure out a solution yet. It seems I need to add the '-55' because these settings do not account for a dynamic sized systray. It seems that the formulas that used to work now only work as if the systray was empty, and more tasks that make the systray wider result in the systray growing without the taskbar shrinking, where as before the two worked in harmony. I think it has to do with exportable variables utilized by taskbar3 but not xtaskbar2? or xtaskbar not recalculating the numbers when they change?
