Always Mouse Wheel is a small portable Windows program
this gives you the possibility when using the mouse wheel
over any window (under the mouse pointer) to scrool via mouse wheel
even if the window is not in the foreground e.g focussed.
The program allows optionally: brings the wheel window to the foreground.
The inspiration was a user suggestion from Q-Dir 3.73 internal function.
But this is a system-wide function for all Windows x64 and x32 systems without DLL and as a portable tool.
So you save a couple of clicks, or switching between windows.
