Finale 2014.5.7098
iMac (21.5-inch, Late 2015)
OS10.12.1

Problem: I can't keep ahold of the measure I'm working on. When moving the slider for new measures, the slider "bounces back" from where I put it, along with the measures displayed. When I attempt an edit in speedy entry, often it will jump to a nearby measure. After trying this 3-4 times, it will generally allow me to input something into that measure. This makes Finale virtually impossible to work in. There's a possibility that it may be a system problem, as sometimes other windows have flickered or redrawn oddly. But I have no problem entering text (as now). Any ideas how to fix this?
