Sometimes when i go to setup room then right-click parameter and select Graph i get the window popping up, but its 0% height (so i have to resize it), which i think maybe is the problem.  Could it be that poser or windows 10 is detecting that the Graph Palette is 0% high and not rendering it on screen?  When i toggle back to Pose, the Graph Palette usually disappears again (though it remains active in window / graph) though.  Is there any file that controls UI Palette dimensions?

I did reboot after factory state setting.  It could be going off-screen, not sure how to test for that, i have only one monitor and one graphics card, and multiple displays not set up in Nvidia..
