Ok, I feel so stupid for asking this, but how in the HECK do I get rid of the pre-set guides in the Helium wireframe? "Clear Guides" only deletes MY custom guides, the pre-set ones never go away. I've checked every conceivable setting, looked through all the layers on every page - I can't even figure out where they're originating from. All those blue lines are starting to make my head hurt..please help! Thanks!
