Once an X session has been terminated, attempts to start
Netscape in any subsequent X session issue in the error:
_MOTIF_DRAG_WINDOW has been destroyed
I am using RedHat 5.2, WindowMaker 0.51.1 (got the same
error with 0.21.1, which shipped with RH), Netscape 4.07.
This sounds like a netscape problem to me. Have you tried Netscape
should be fixed in XFree86-184.108.40.206-24
