Cannot make new directories via DWC

Cannot make new directories via DWC. Using Chrome browser. Windows 10. I can make new directories if I remove the sd card and connect it to my computer.
I have re-formatted the sd card.
It is a sandisk 32gb class 10.

What happens when you try to make a new directory?

Hello dc42,
All that happens is the cursor changes to the hour glass and that's all. the directory doesn't get made.
