This is a *very* old bug that has been around for at least three versions and, although it is reported time and time again, simply hasn't been fixed (although it has been acknowledged). I guess it's more important that we get some fancy new feature that nobody will use before the core functionality is sorted </sarc>.
Yes, I'm a bit cross about this because it *has* been going on for so long and affects my daily workflow to the extent that every time I use DR I'm reminded that it exists.
The problem affects Windows-based systems and any numeric field that can be altered by mouse-drags.
Hello BMD? Are you there??
