How scroll MSFlexGrid with mouse-wheel?

I have written several VB6 applications that have MSFlexGrid controls on them. On some of the user's computers the users can scroll the rows in the flexgrid using the wheel on their mouse. On other user's computers the mouse wheel does not scroll the flexgrid rows.

I was able to get the mouse wheel to work in the VB6 IDE by downloading and registering this fix from Microsoft:


But I still can't figure out why the mouse wheel sometimes works and sometimes does not work on the various user's computers when they run the various applications exe's.

We do not use any Intelipoint software of any kind, so going back to version 4.12 is not applicable for us. We use Microsoft's standard driver (built-in XP driver) 5.x

This question was posted earlier but I could not get the answer to work.  See comments at end of question:  http://oldlook.experts-exchange.com:8080/Programming/Programming_Languages/Visual_Basic/Q_21345809.html

Any ideas? Thanks.

try http://www.andreavb.com/tip060008.html

this gives a different method but also the definitions of '1.  "WM_MOUSEWHEEL"   just need to find the definitions of the other 2 const or structures.
