I run MMW version 4.1.21.1875
No, I don't have any extra addons installed, just the standard installation exe file.
Yes, File > Exit also fails to close.

Which version of MediaMonkey are you running and do you have any extra Addons installed?

I presume File > Exit also fails to close?

When I try to click the X/Close button on the top right corner of the MMW window the program doesn't close like it normally should and like all others apps do. I click on it but everything stays the same. I can click many times but nothing happens, the apps just keeps on showing as it already does.
Same problem with when I try to close it by going to its icon on the Windows task bar and then waiting for it to pop up and then click the X at top right. It also doesn't close it.
Same for when I try it by right clicking its icon on the W task bar and then choosing Close Window.
So all 3 methods fail to close the MMW app on my Windows 10 Pro (w/ all latest updates). And I have the most recent v of MMW installed.
