737 Panel Duplication

Hi!I'm constructing a home cockpit and I want to use PMDG forit, because I want to avoid the purchasing of ProjectMagenta, and anyway, I like more the displays of PMDG thanProject Magenta. So I need two pair of displays, two of thePFD and two of the ND. Normally the plane displays one pairof them. I had an idea how I could duplicate it. I definedtwo other windows in the aircraft.cfg, and I filled them inwith the data of the original PFD and ND popup. By this wayI've got the two pair of displays and they can be movedanywhere I want. But...now comes the problems:The two new displays I've defined are not always active.They are only active when I activate one of their windows.But if I click anywhere else with the mouse (main screen,overhead etc) they become passive and freezed. The otherproblem is: when they are active and displaying paralell-lywith the original displays, all the four displays are notdisplaying continuously. They are refreshing at about onesecond.All in all: How can I double the PFD and ND popup displays without freezing or long refreshing time? Do you have any solution for this problem?ThanksAdam
