Does anyone think it's possible to have a player's window change to another window in the dmf. file, during runtime?

winshow(src,"WindowThatsMeantToShow",0) // Hide old one
winshow(src,"NewWindowNameHere",1) // Show new one
You could always use child panes, and swap their left/right properties to whichever window you want to display.
