When one depresses +/- buttons in a spinbox fast (say 2Hz) multiple times, the spinbox value is correctly updated, but the buttons are frozen and don't get visually depressed.
tk/library/spinbox.tcl has <Double-1> and <Triple-1> actions that don't check $Priv(element) nor change the look of the 'buttonup' and 'buttondown' elements.Probably they need to call an abbreviated version of tk::spinbox::ButtonDown before they adjust selection (Note that ButtonDown also adjusts selection, so care is needed).
