After lunching Quicken for anywhere from a few minutes to a day, the Memorized Payee List shown when I enter a transaction shows all payees in blue. Upon initial launch, only one of the entries is highlighted and I can scroll to the line I want. See below for screen shot.
I have reported this issue before and was instructed to reinstall Quicken - it did not help. I also did a Super Validate of my Quicken file. Several other people have reported this issue, and I have not seen any report that is has been resolved.
