'current' tag .....

[pehr anderson]

Dear Martin,

It sounds like you just want to capture the "button-down" "button-up"
events and track that separately. In you code where you notice that the
mouse is over your item you can test on each tiny mouse movement 
whether you are in the button-down state.

Alternatively, you could only enable tracking of movements whent
the button is down, and disable tracking of movement after a 
release event.  I'm not sure how to hook and unhook the mouse-movement
event capture but that sounds like the "right" way to do it.
Very low computational consumption when the user jiggles the mouse
without clicking the button.
