Unable to Resize PopUp Panels

I am trying to resize the 2D panels of my FeelThere Embraer 175.

I have 6 "popup" panels, PFD, MFD, EICAS, MFD2, PFD2 and AP. When I select them from the menu, they are displayed grossly exaggerated in size. I wish to resize them, but it appears I'm unable to click to undock and resize. When I click on the panel, it disappears.

How can I enable these panels to resize and reposition them?
