Running Mac OS 10.11.4
Model Identifier: MacPro6,1
Processor Name: 6-Core Intel Xeon E5
Processor Speed: 3.5 GHz
I'm runnning two Mac Thunderbolt monitors. My main working window is in the left monitor. All of my tool menu's are arranged on the right monitor so everything is easily accessed. When I click a pull down for line weight, gradient type, or effects the pulldown shows up in the correct location where my mouse is clicking, except it's on the left monitor. Any help would be greatly appreciated.
I finally found a way to fix this. In the Mission Control preferences panel turn off "Displays have separate Spaces". After rebooting the machine with this change in place the pull down menu's stay on the correct monitor.
