I've surrendered and switched my secondary monitor to the right. Now WinWarden works fine for me.
Kruskal: glad to see that sorted out.. sometimes simple solutions are the best..
Well it didn't turn out so great because WinWarden doesn't recognize that I have told it to display on non-existent territory when I am in single monitor mode. Maybe my situation isn't typical, but I switch a lot -- I only use dual monitors when I am watching media and have a TV available.
I think I'll just give up on the whole thing.
WinWarden would have worked despite this using a left secondary if it worked in that case at all since I would be telling it to place the window at a low X position and that would exist in either case.
Thanks for your good wishes -- Vincent
