It will only float and persist on the monitor where the track view is placed I believe. At least in Cambridge.

Not true here ...

THis happens to me pretty often, especially with older projects. If you look around you'll see a "ghosted" piece of the dock when it's supposed to be visible. If you click on it and then do "D" to hide the dock and "D" to pop it up again it should come up as advertised. It's weird, but I've gotten used to it.

No not true here either 

I've found the hidden icons to get to the Multidock so the problems solved but man the Multidock is now a glitchy piece of Sonar in this release. It flickers and crashes Sonar.

Did you try a roll back, and update. May be worth a try being you seem alone in your issues so far.

Sorry you're having so much trouble Mike.  Glad you at least found a partial solution.  I wonder what's causing you so much trouble with it on your system.  Mine's behaving just fine, no matter how much I load the multi-dock up.  Since it now seems to be more of a display issue for you, have you checked for updates for your graphics card drivers?

Yeh, all checked. The weird thing is if I go back to Cambridge it's all smooth and works fine. In Dorchester it's a bit glitchy. With the newer features that have come out I've been experimenting with new workflows maybe time to go back to scratch on how I use my second monitor.

Also working better than ever here.  Scrolling is nice too.
 
I did notice that if there aren't views open in the dock, the detach glyph isn't visible.  You have to open at least one view for the detach option to show.
