Ken,
Had that problem too. First I had to disable the native bindings like
so:
bind .lb <1> { }
...and then:
bind .lb <1> [code $this onClick]
You need the blank space between the curly brackets.
A year ago I understood why, when Michael McLennan explained it to me...
however I cannot recall this moment of illumination... ;-)
Cheers
Rob
