Hi, I just got the GUI version of mplayer working. What I find is that whenever I switch to full screen mode, and I try to move (drag) the GUI window, mplayer crashes. I recompiled it with --enable-debug, ran it through gdb, and here is the backtrace: Program received signal SIGSEGV, Segmentation fault.
