Excel Find and Replace Box

[Caco646464]

When I hit CTRL+F in Excel now, the search box is popping up as a full sized window, that covers the whole screen, so I have to minimize or close it to see the whole sheet again.  It used to just open up in the small window that you could move around. 

To make it more fun, it doesn't happen every time.  Just most times. 

There has to be a simple setting for this somewhere. 

Any help would be much appreciated. 

Thanks,

John

What happens if you double-click the title bar of the Find and Replace dialog?

@HansVogelaar  of course, now that I have posted the question, it hasn't happened again since then! I'll reply what happens if the big box pops up again.

So now it happened again. If I double click the title bar it just expands to the whole window (I have an ultrawide monitor that is separated into three sections with FancyZones).
