I would rather have some ini file than another tool storing stuff in the registry.... or if you are willing to keep the tool updated for all time it would be possible instead to create an internal list of such drivers that the tool would check against when starting and ignore a driver if found in it.

@Kukubau: not that LoB needs defending, but he is right, when talking about dtools inner workings better to keep that off the board (in this case asking about the drivers name), after all we want to enjoy DT4 for as long as possible!
