I've tried to start a thread a number of times now only for the grey screen with 'drop photos here' to wipe out the page then not respond to anything including dropping pics. The first time was when I tired to drop some pics. The second time it was when I highlighted some text on the page and the third time it did it it wasn't even the open tab. I am at a loss as to why you can't 'cancel' the grey page, that would be enough, but it seems to get locked. If it's an issue with my machine, ok, just wondered if it's something anyone else has experienced.
