I replying to my own post. I discovered if you go into the "tool's Tab then "Fredo 6 Collection" then " Reset Vignette Stipe Position" the tools show up top dead center of the Screen. I wish more plugins had this feature. I am constantly losing dialog windows because i bounce between different monitors .
Sill unresolved is the need to make the main screen option. I still can not get the vignette to show up on my big monitor un less i go into display settings and "make this main display"
I am not sure of how to report problems.. But I'm seeing a little icon of the the last material I used in Thru paint. is jus shows up as a 1/"x1" thumbnail in the canter of my screen . Also it seems like the new SU upgrade is making fredo tools harder to load/ reload too
