1. Does anyone know what determines the scroll rate when a user clicks on the mouse wheel and then moves the mouse up or down to begin auto-scrolling? Is the mousewheel auto-scroll rate controllable via a VFP SET setting, system _VARIABLE, or SYS() function?

2. I've noticed that in the auto-scroll behavior only works in my grids if the mouse is near the left edge of the grid. If I begin the auto-scroll process near the middle or right edge of the grid, the auto-scroll will "randomly" stop scrolling for no apparent reason. There seems to be no pattern as to where the scroll stops. The only thing I can think of is that the records where it does stop are wider than than the width of the grid and perhaps there's a link to VFP 9's new auto tooltips for grid cells with visually truncated values? Note that the auto-scroll doesn't stop at every wide record, but when it does stop, it stops on a wide record.

Any thoughts on my questions or observations?
