GirnBlanston: BOOOOOOM, the play button has disappeared and I can't get it to open. Sooooo, I have to leave the site and the browser
Yep it happens to a lot of people too, asd I write this the Play Button (Login Panel) is revolving around at 100% "Teeing Off" and will just sit there like that till i click on another link and then it may load in properly.
What I do find can sometimes help other than crashing the browser down is a Force Refresh of the browser. Usually hold down CTRL while pressing F5 or your 'Refresh' button. ( On a Mac it is SHIFT & F5)
This dumps some of your browser cache and reloads your current page.
