Add Account - new interface - list doesn't scroll

I am experiencing the same issue using Quicken Classic Deluxe for Windows.

I am not able to scroll through my accounts list to link existing accounts (to their corresponding financial institutions) unless they are displayed in the popup list. That popup list includes hidden accounts, and I can see about 39 accounts with my display settings. I cannot view the rest of my accounts. I have decades of account history and close to 60 unhidden active accounts. All relevant active accounts have functioning downloading relationships with Quicken. My Quicken data and backup files are stored on my local drive and synced with the cloud.

It would help if hidden accounts were not displayed by default (or if an option were presented to hide them from view), but that does not address the issue of not being able to scroll (or query) to see all active accounts, beyond a couple dozen in the popup list. I don't recall having this issue in the past and I cannot recall with certainty when I started experiencing it, or whether it started with the most recent Quicken updates. I do recall initially attributing the problem to what I hoped was a transient glitch that would resolve with subsequent Quicken updates. However, this is now a persistent problem.

I have just submitted the above info to Quicken Help.

What prompted the need to link previously working links has been some recent inconsistency in Quicken downloads from financial institutions. Without any obvious pattern, Quicken sometimes fails to pick up activity in spite of having valid credentials that had been working. My fix was to deactivate and then re-establish online access for those accounts. Today it was for Citibank credit cards (that fortunately appeared on the non-scrolling list of accounts). Those two accounts use separate sign-on credentials. Last week I had an issue with one money market account with my credit union. Six other accounts at that institution, which use the same credentials as the money market account, downloaded activity to Quicken successfully. The problem in this last paragraph is entirely separate from the account list scrolling problem, which is the main focus of this post.

I am having a variant to this issue. When I tried to download yesterday (March 14), I found all my linked accounts were not showing in my One Step Update (OSU) list. When I opened my account list, ALL accounts had their transaction download flipped to off.

When I try to reconnect the accounts, I found three different types of behavior:

1. With my Fidelity accounts, I was able to connect to Fidelity and select all my active accounts but when I attempted to link them in Quicken, none of my accounts showed in the list, and I experienced the same inability to scroll as all my old and hidden accounts were populating (including old inactive Fidelity accounts).
2. I was able to reconnect my active Bank of America and Schwab accounts.
3. Whn I tried to connect any of my credit card accounts (AMEX, Chase and CapitalOne were the ones I tried), I received a sign in failed response ("sign in failed due to a time out or connection failure").

I reported the problem yesterday via the Report a Problem link along with the related files.
