Hi, I upgraded to 5.3 recently and this seems to have had an effect on multiple monitor support...
My monitors are now turned around... main display is on the right instead of the left and on my MacBookPro, the external monitor is my main monitor and the retina display is the extended.
When I got to change these under display properties, the make this my main display check box can't be selected and is greyed out. I have googled this and can't seem to find any answers... I tried changing a registry setting but no good.
I am on a domain and unfortunately do not have access to domain policies... however, my view VM and my physical desktop are both in the same OU with the same policies applied and I can change pretty much everything on my physical desktop.
I am kind of out of ideas on this at the moment and no, it isn't that bad, but a bit opposite to the way I usually work and I'm getting a bit of a crick in my neck from looking sideways at the extended display ;-)
Ceers
