Dual monitor problem with Pro Tools 11.2.2

Dear Colleagues,



since I updated to PT 11.2.2 from 11.2.1 it seams to be impossible to expand PT on a second monitor.



This is not exactly the behaviour I like to see since I've always been able to have the Edit Window and the Mix Window on seperate Monitors.



Is this a bug or a feature - or does the problem sit in front of the computer?



Best regards,

Wolfgang
