A few months ago I changed a setting (I can't remember what) thinking that Quicken would categorize all future transactions to existing payees as I had been manually categorizing them. Instead, Quicken changed all my previous (and new) categorizations to categories I did not want (using some type of logic built into Quicken I suppose. This wrecked my entire Quicken file (18 months of work). Is there a way to fix the categories on all past transactions back to the way I chose? What setting should I change so that Quicken does not do this any more in the future?
