2D panels undock on multi-monitor setup
I have a multi-monitor setup where I managed to undock the captain, FO, overhead and center forward panel (with the fmc) and moved them to a different monitor each. Now I'd like to undock the center aft panel (with the ARCDU) but don't get the option to, with a right-click on it. So there's no means to move it from the screen it is displayed on. Is there a cap on the number of 2d panels which can be undocked or am I missing something?
I've got the Pro edition of MJC8 Q400 with P3Dv4.5 and a Windows10 system. 4 of the screens are on one graphic card, whilst the 5th is on an second graphic card.
Thanks for your help.
