Windows 10 App window won't reduce by dragging.

On my Windows 10 machine, I just ran an app which somehow caused the window toget larger than I want. I tried dragging the sides to shrink the window, but the double-headed arrow wouldn't "grap" the side, so when I dragged the arrow, the side wouldn't follow. This happened out of nowhere, and I'm not sure what happened or how to fix it. I'm also worried that this "bad habit" might spread to other apps (like Firefox). How do I make the window smaller? (Note: this occurs in"reduced-size" mode, not full screen.)

Hello, Roger. Welcome to Windows Ten Forums.

How long has this been happening? Have you rebooted the machine?

It just started this morning; no I haven'[t rebooted yet, but will this afternoon

Ok. Can you reboot now to see if that resolves it? It only takes a minute.

Also, have you installed any programs recently before this happened?

Is it possible your Notebook/Laptop has changed to Tablet mode? Check the Notification button on the Notification Area, right-side of the clock. I noticed that on one of my Touchscreen Notebooks.

I just rebooted--no difference. Also, the machine is not in Tablet Mode. and I haven't installed anything.

Obviously something got damaged. You may want to try these:

If those don't work, try this:

System Restore Windows 10

Or if worse comes to worse this:

Repair Install Windows 10 with an In-place Upgrade

I tried the "Dynamic Duo" (DISM and sfc), but no change. One observation: when I start the program (MalwareBytes) it opens in its normal size; when I maximize it and reduce it again, it falls into the situation I described. Does that suggest anything to you?

Sorry for the delay. Christmas-busy yesterday.

Did you run sfc at least 3 times as the tutorial says?

I'm at a loss and thinking it may be your video driver? Has that updated lately? Is it up to date?

There is one Registry modification I saw that may help. I'll have to search for that again.

Does holding Windows Key + Down Arrow key or any arrow key work by any chance? We'll see if the keyboard shortcuts work at least.
