For a couple of weeks now, I have had a frequent issue with Quicken Classic for Windows lagging when opening and shutting down. During entries and paying bills etc. it is normal.
At first, I was lost because about that same time, Windows 11 introduced 25H2, and my ISP did an update all at the same time. After talking to my provider, they tested and confirmed things were normal on their end of it.
After diagnosing Windows as much as I could, I found out that when disconnected from the Internet, Quicken works fine, even better than it had prior. However, when logged into the Web, the symptoms all come back. After more research, I saw where 25H2 had a glitch where applications relying on certificate-based authentication had a problem, so I tried Microsoft's temporary fix, but it offered no remedy to my situation.
So, if anyone out there has had this issue and found a fix, I would love to hear from you.
