[PD] Setting properties of number object

I tried this, and somehow it prevents the slider from updating 'itself'
through a feedback loop ( It is getting the data from the player (veejay), and
sending out data to veejay to change the position when I drag the
slider...).
Althoug it doesn't drag very smooth yet, it seems to behave more like a
gtk slider already( that is, don't update from current frame until
dragging stops)

But I don't understand why?
