Paul,
To waive a drc, go to pull-down menu, Display => Waive Drcs => Waive. Then just select a drc marker and it will be waived and disappear. If you want to see it again, you can go to Display = Waive Drc => Show,and it will redisplay a drc marker that is rotated 90 degrees to indicate that it has been waived. You can also restore(undo) all or individual waived DRCs from the same pull-down menu.
Also, to see waived DRC status go to Setup => Drawing Options (status tab)
