The Bare Minimum Tordex Wheel works as advertised...it scrolls the window pane under your pointer, instead of whatever has focus, but stops dead there. It does not work for anything BUT window panes or other items that are not bound to scrolling already, such as combo boxes or sliders (which plenty of other mouse interfaces do...I first enjoyed these features on a Radio Shack mouse about a decade ago). Also, when scrolling non-windowpane items that do have focus, like combo boxes, items get skipped, even when scrolling at minimum speed.I'm also having to use additional software to enable mouse wheel ...
