Cool plugin. Although I am experiencing a weird bug:

- it only draws the arrows ONCE by any event the pd window is redrawn

  - events that I tried and worked (thus the arrows magically appear): save patch, move patch window. change desktop.

  - events that do not do nothing: moving stuff inside the patch (moving an object, drawing new coords).

Could be an X/ubuntu issue, maybe its just here. I have to try on other machines (anyway: Ubuntu 10.10, gnome, pd 0.43 extended latest nigthly build, your plugin was downloaded from the list, second mail you sent with the bugfix)

best regards,

pedro
