great - i should mention that when DBE auto-creates sample points it starts in the upper left hand corner of the image and goes down to the bottom left, then steps to the next column to the right and repeats. therefore if you pick a sample somewhere in the middle and delete it, DBE selects the next sample, which is the one below the one you just deleted. hence you can start at some position in a column of samples and quickly delete samples beneath that sample by repeatedly hitting the delete key on the keyboard. that's what i meant about deleting a bunch of samples.
