How do you set up 4 Panadapters so they all display signals.

When I first start my 6700 the first Panadapter and Slice pop up as designed, and if I generate 3 more Panadapters, before I do any thing else, I get the signals showing up on each Panadapters as they should. However if I have been operating and selecting other functions right after the first Panadapter start up, and then add new Panadapters the second one shows signals fine, the third one may or may not display signals and the fourth one does not show any signals at all. If I close the last 2 Panadapters and then restart the third one it generally will display the signals. However the fourth one restarts without a signal being displayed. It seems like there is a special set of steps to go through to get all four Panadapters to display signals but I can't seem to figure it out. I have to restart the radio to get all 4 panadapters displaying signals. Once they are working I seem to be able to do any thing I want to do. Has any one else seen this problem?
