Like many people, I have PF3 and other GUIs on a second monitor and run my sim on the main one. This works, or used to work, fine.
Now I have installed the 3.10.12 update, the main PF3 GUI is where it was, but whenever I open the Options 1# window, it now does so split across my two monitors. Nothing I have tried fixes it. It used to open up on my main monitor, even though the main interface is on the second, but that was OK: split across the two screens like this is not. The position of the Options window in relation to the main interface has obviously changed (and is not user-customisable).
How can I get things back to how they were before I updated PF3 today (short of uninstalling the updates!)? Is reorganising all my app windows on the second screen to accommodate the PF3 options window my only 'option'?
