I added
Code:
MOUSE_BTN0_DBL vo_fullscreen
to my mplayer's input.conf for fullscreen on doubleclick, but it doesn't work correctly.

It will work correctly for a little while, after which point all the keybindings need to get pressed a bunch of times before they get recognized by mplayer. ie. it takes 3 or 4 pushes of 'v' to turn off subtitles, or mad rapid clicking to get it to go fullscreen.
I have not found any info about the DBL double click bindings giving people problems, does anyone here know anything about this?
