>>>I have a grid with four rows and five columns. All cells for all records are always visible so there's no need to scroll in any direction.

>>>When the user moves to the bottom row using the arrow keys, the grid scrolls down one row. Also, since this grid only (always) has four records, the new bottom row is always blank.

>>>I have this same problem moving the cursor to the far right column, the grid scrolls to the left. This is handled by making the grid about two pixels wider than the columns actually require. It's ugly, but it works. Unfortunately, the same approach does not work for vertical scrolling.

>>Personally, I don't see a problem if users will see one more empty line on bottom of a grid. For example, nobody complains that Windows Explorer shows empty space on bottom, if number of files is too less to be scrolled. Also note, that sophisticated user could resize width of row and your problem will reappear.

I've used grids in other forms where this was not a problem, but I must keep all four rows visible as the user moves around in the grid.

VFP3 doesn't have AllowRow/HeaderSizing properties and here I used once MouseMove and/or MouseUp events to catch user's attempt to resize. Putting code like This.RowHeight=Thisform.PermanentRowHeight will do the trick.
