Nothing is functioning when its grayed out, only restart solves it.

James from the support suggested checking mark here http://prntscr.com/k4s11j and that is what fixed it.
He says its a known bug. Hope this solution helps someone.

No joy. After few hours I went back to open it and everything is grayed out and its stuck on this screen http://prntscr.com/k4ldbs

Did not know I need a ticket number. I was hoping to get help here. I created ticket just now Ticket Id : #92679
Just uninstalled/installed. Will see if it will help.

Its been over 6 days and there's no reply from support?

Rebooted in the morning now in the afternoon same issue http://i.prntscr.com/DAj329kET9ijKJyZfUtPlw.png

It happens randomly. No other open dialogs. I can not send anything because everything is grayed out.
Had to reboot computer to be able to open it.
