Hmm. But subsequent presses show similar behaviour, so at least by 
second time it should be in the cache. From my limited understanding of 
keypress handlers I initially thought that the wm goes through its 
handler and then by the time the plugins key handler is run other 
windows try to see whether it's 'their key' so plugin goes last and 
always after all other even handlers. I may be way off though :)
