windows XP smplayer -send-action not working

[KevinA]

in ubuntu all i have to do is smplayer -send-action pause and the current instance of smplayer pauses
in windows, it spawns a new instance?
do this make smplayer unscriptable in windows?

is there some other way of doing this?
Thanks

Do you have the single instance option enabled in preferences?
