I use Quicken Premier and I installed the 2018 iteration yesterday.
A Quicken annoyance that I have been dealing with forever is located in "Bill and Income Reminders." In this feature, Quicken volunteers to add arbitrary transactions to the list of memorized items. So I have to do a few mouse clicks to decline. Again and again, a few times a month.
In QP 2018, it got worse. I *cannot* delete the item from the list of upcoming memorized transactions. There are buttons "Yes" and "No" to accept the transaction. If I click "No," I get a dialog box that asks a further question "is this transaction blah blah dated blah blah". No matter how I respond to the dialog box, the memorized transaction remains.
Annoyance x 10.
