AcGIS Engine 10.1 Mouse Wheel zooming

[ScottMcNeil]

I need change the default behavior of the map control in (.Net app) of the mouse wheel for zoom in/out-- default is roll forward to zoom out, and I need roll forward to zoom in.  In 9.3.1, I was able to change the behavior using the registry setting found in this thread

however this does not seem to work for the latest version.  Anyone know how to resolve this?

TIA

I should add that I can reverse the zoom direction in ArcMap 10.1 using the options setting, but this has no affect on zoom behavior in the  Arc engine application (not that this is a viable option-- just thought there may be a new registry value that might be useful).

ESRI finally provided the answer to this.  The registry setting is in a different location, but works the same as before.

HKEY_CURRENT_USER_\Software\ESRI\Engine10.1\ArcMap\Settings

add DWORD value, ReverseMouseWheel = 0
