Waiting room and overlapping floating window

Description
I have waiting room enabled. There is a suspension window that appears on top of the participants waiting and does not allow me to move the window to click admit. How can i fix this - See screen shot below

Error
Floating windows do not allow clicking on “Admit” as they sit on top of the button and cannot be moved aside.

Which version?
1.7.5

Hey @rsatyan,

Can you try upgrading to version 1.7.6.

Also please make sure you are including the required CSS files.

Thanks,
Tommy
