I have a chart containing a spinner button. Each time the user presses an
up/down arrow, my worksheet calculates a range containing the next/previous
set of data.

When holding the button down, it used auto-repeat, quickly scanning through
sets of data. I have just upgraded my sheet, adding an extra spinner, so
that the range-pointer can be moved left and right, as well as up and down.
Now, the buttons no longer repeat, and I have to keep pushing the mouse
button each time I want to go to the next set.

Does anybody know how I can regain the auto-repeat feature of the spinner
buttons?
