Notifications showing up in center of screen

Thanks-- I do have the chrome window still open-- does that matter?

What about the main issue of notifications and desktop sticky notes moving to the center of the screen? It's as if the resolution is being adjusted or something (but I haven't adjusted it).

We fix what we can and hope for the best. The sticky notes could be odd hardware or driver issues. My thought is to stop Chrome first and hope that helps.

As to Chrome open, if it's open Chrome can do stuff such as play etc. Why is that a mystery?

It's a mystery to me because it happens after the computer restarts, it's on the lock screen, the videos had already finished before the restart, and I've never seen this with any other computer.

My main issue is the notifications/sticky notes moving. I tried what you suggested for chrome and so far I haven't seen the videos playing by themselves, but this didn't fix the other issue. I don't think they're connected-- has nothing to do with chrome.

Lock screen doesn't tell apps to stop. And I think you wrote the Stop Chome! helped on one item.

As to the sticky notes moving. https://answers.microsoft.com/en-us/windows/forum/all/my-sticky-notes-keep-moving/c82c2be8-3e2e-4fe6-aabf-7394075bdc3b is telling me sticky notes was buggy before. Since there are a few sticky note apps I can't do much research but know that Microsoft apps tend to be awful or break and good luck getting them to fix them.

Example: Email apps that came after Outlook Express. Folk ask me how to fix that and I write "Thunderbird." My long answer is that I can't count on Microsoft's free email apps to be stable or work right. So my lesson learned is to not count on them.

Edited for grammar.

That would make sense, but it's also notifications doing the same thing-- all notification bubbles-- which wold normally be on the bottom right of the screen, appear in the center right where the sticky notes move to.

The notes and bubbles sounds to me like a Windows or driver issue. That one may have to be taken back to Microsoft.

I wrote but it was just a hint that I can't guess what sticky notes app you use. Doesn't matter since I was only writing about the Chrome issue. My reply was hoping that ending Chrome would stop Chrome playing while on the lock screen.

One of the recurring fixes to Windows issues is to turn it off and on again. Try turning off notifications on the lock screen, test and maybe turn it back on.
