I'm staying on Quicken 2013 Premier for Windows.
The "sort and search" methods are very manual processes - I agree that Quicken ought t be able to add a feature that enables one to quickly search and identify duplicate transactions (follow Excel's model!) - certainly would have helped after I had to revert to old style of downloading QFX files in order to "rebuild" my accounts after a horrid experience with the new WebConnect updates - security is important and I support 100% but I just wasted an entire evening rebuilding the majority of my bank and credit card accounts to get them to reconcile - having an easy way to identity duplicated downloaded / imported transactions would have helped.
You say "delete the duplicate entry". But how do I delete it? There used to be a delete key stroke but I can't find it on the new program.
