I am not sure why there is a difference between IBO3 and IBO4 in this
regard - because IBO does not explicitly call the generic OnClick
event itself (that happens in the VCL). It may be the explicit
control over the scrollbars now being applied.

However I would suggest that you use OnCellClick for your code, then
you will be sure of not getting the code executed when scrolling and
you can control whether you want the code executed on title or border
cells.

Let me know if that resolves your immediate problem.

BTW: In regard to the event code you sent, instead of tracking shift
key states via keydown/keyup you can use the API as in...
GetKeyState( VK_CONTROL )
