Adrian,

Magic interacts with the mouse like a standard program. If the mouse wheel scrolls up/down in browsers, excel, word, etc, it will do the same in Magic.

The code below will force the mouse wheel to only scroll one line at a time while in your application regardless of its Windows setting (which by default is 3 lines).

In Main Program you can do the following:

1. Create the following global variables

1. In Main Program Task Prefix do the following

Note: The DotNet expression is this:

DotNet.System.Windows.Forms.SystemInformation.MouseWheelScrollLines

1. Setup the following events in Main Program (the expressions on the right are: NOT(gMouseWheelDisableCheck)

For the above Events Previous Row and Next Row, The “Propagate” property is set to the following expression:

                gPropagateMouseWheel? OR KbGet(0)<>'<>'

If I remember correctly, that should do it.
