when winamp is playing it will just jump to the start of the song
plugin.hwndParent might have changed but I'm not sure how that part works

(didn't find a goog tut on it either).
I'll try your suggestion and post the results
EDIT:
i tried your line of code and it worked in the config() function but not in playPause().
think your right about the value of plugin.hwndParent having changed, got no clue on how to fix that though.
