Saving undocked window positions

Hello everyone,

This is driving me nuts and it's hit and miss. I'm running 3 monitors. I am in full screen mode. I undock my PDF, ND and MCP and drag them and size them in my left monitor. Then I undock and drag the overhead to the upper monitor. So now I have everything sized and in full screen mode where I want them. Then I save the flight and call it..say 3 monitor setup. The problem is, if my FSX crashes or I have to restart for some reason and I load my 3 monitor setup the undocked positions aren't saved. I have to drag and re align all the windows again . Is there a proper way to do this that when a person loads in a flight, all these windows will be in their respective places on each of the monitors? If there is, I'd sure like to know how to go about it. I dont know if this is a windows or a pmdg issue.

Windows 7, 8gb, i5 AT 2.7 pmdg 737ngx

Thanks,

Ed
