Lenovo touchpad scrolling

Lenovo 3000 N100 touchpad vertical (but not horizontal) scrolling worked in LabVIEW

Lenovo SL510 touchpad scrolling does not work at all (in LabVIEW, not other Windows windows: explorer, paint). Mouse scrolling works fine

Any other touchpad developers who encountered this and can help?

Where is bug: in LV, Lenovo (or my hands =)? 


PS: Horizontal scrolling I mean from any point of the window, not move mouse over horizontal scrollbar and use regular scrolling.

Rajesh, have you seen touchpad horizontal scroll working in LV? 

The scroll works in other programs - the drivers are installed. In LV help it works.

I think, LV handles mouse on front panel and block diagram at a lower level. Touchpad scrolling starts as mouse down (light touch (tap) is mouse down) and it is not processed, that touch may become a scroll. It can become a double click - it is handled. Try processing double click as an event. First it gives you single mouse down (not a double click), then a second mouse down with double click flag true.

I am not aware of internal LV functionality, but some of the forum members may be, they can at least agree or disagree (with arguments) with the above conclusion.

If I am right, the scroll is not supported and will not be supported for a long time. 

Or I may be wrong, then I need an example: Minimum: "it works". Better: "solved this that way"
