It certainly happened to me Karl. I purposely moved my DAW onto a super duper laptop and I made sure that said laptop had the capability of running two monitors.
I already had two large monitors from my other DAW and I used to have the main Sonar window on the main (left) monitor and my Console was always open on the right monitor.
When I first set up my laptop I made sure that everything worked and tested my "external" monitors and all was fine.
I have not used those monitors since that day. Multidock has to be the reason for that, for me. I must admit that I've not bothered with screen sets. Probably due to my simple-ish work flow and I'm finding that toggling between track view and console, using D, is good enough for my needs. I find that I never need to really see my console while tracking, and I just have track view visible. And also while editing too. And when I'm mixing and generally messing with effects and levels, I switch to console. And I have console view, or the Multidock fully maximized.
