Ubuntu – 16.04 – Copy Dialog disappears and nothing seems to work


I am in the middle of a massive file transfer.
The file transfer window either never shows up or disappears when I move to another folder.
I have tried everything to bring it back and no, i did not press Super+D keys either.

The show copy dialog option you get when you right click on Files Icon on the left of the screen is not working.

Alt+Tab, Alt + ~ also not working

It is quite a troublesome thing when you cant figure this status, especially when your work involves a lot of copying/moving folders.

Please help!
