I have a sunporch. All the windows have screens than seem to have been added afterwards. I have tried everything, but can't see how to remove either the windows or the screens for cleaning. I have attached a bunch of photos. Any suggestions would be appreciated. I tried pushing the window up to free it from the bottom track, but there isn't enough slop to do anything. Any help would be appreciated. (removing the molding that holds the screens in would work, but isn't really practical).windows1.jpgwindow3.jpgwindows2.jpgwindows4.jpg
