Scroll wheel not recognized

I have been using strokeit for a year, I am very familiar with the program and editing/creating/ my own gestures but cannot seem to get the mouse wheel to be recognized as a gesture.

I have my gesture button to hold set as my right mouse click. When I hold my right mouse click then scroll my wheel up or down it does nothing. I uninstalled strokeit, reinstalled a fresh copy and overwrote all my old settings and gestures and still nothing. I tried on a different computer, nothing. I went to 'learn gestures', hold the right click, push wheel upward and it does not recognize it.

If anyone knows what could be wrong let me know. I am using a logitech dual optical mouse.

Update: After uninstalling the Logitech software that came with the mouse strokeit now recognizes the mouse wheel and I can use it as a gesture.

FIX: Try and uninstall any mouse software you have, this includes anything that assigns your extra mouse buttons for special functions.
