Windows 10: System windows suddenly scrolling on mouseover

Dell Optiplex, Windows 11, fully up-to-date according to Dell Support Assist and Windows Update. Been using this computer for a couple of years; today, it started to exhibit a weird behavior: system windows scroll uncontrollably on mouseover. Only system windows. Using Chrome right now, no problem. PowerPoint, no problem. But if I click the time & date in the taskbar, the calendar scrolls uncontrollably. If I open Settings -> Bluetooth & Devices, the list of devices scrolls unstoppably to the bottom.I've found lots of advice talking about replacing the mouse, checking the driver, et

Mouseover/Icon text is suddenly huge!


Hi...

I noticed recently that text size of the mouseovers on my system changed to a very large size. I'm not sure if I inadvertently hit a shortcut key or something that did this or not, but I can't seem to find where to adjust this text size.





I also noticed that this large size also seems to affect a few applications (like PowerPoint, Adobe PDF Viewer, etc.) but not others (like Word, Excel).






Any help you can provide would be appreciated.

Thanks,
Frank

No, I'm not using any Magnifier apps.

I haven't changed my default settings. They are as follows:





....and here are the setting in Advanced:





as noted earlier, I see this also in Powerpoint but not Word or Excel. The following screenshot is of Word (which is all correct and normal sized) against Adobe and Powerpoint both. You can see the obvious differences in font sizes.....





Thanks,
Frank

 

Windows 10 Tweaks

Pressing “Windows+Pause Break” (it’s up there next to scroll lock) opens the “System” Window.

Windows 10: In the new version of Windows, Explorer has a section called Quick Access. This includes your frequent folders and recent files. Explorer defaults to opening this page when you open a new window. If you’d rather open the usual This PC, with links to your drives and library folders, follow these steps:

• Open a new Explorer window.
• Click View in the ribbon.
• Click Options.
• Under General, next to “Open File Explorer to:” choose “This PC.”
• Click OK
