Hi Rick, it kind of sounds like that may have been a bug.

Try this attached QuickTrim plugin instead (instructions for installing a plug-in here.), it will allow you to trim curves by swiping across the pieces you want to discard.

For this one you don't need to select anything, just swipe over them. But if you do have any selected it will only target those selected curves.

Works like this (here with repeat checkbox turned on):

EDIT: Minor update, if using selected objects make result selected too.

EDIT: Jan 23 Another update, fix for swipe mistakenly targeting 3D curves in some cases and also not skipping hidden/locked curves. Also now only tries to intersect curves on the same plane as the swipe.
