🤔 Strange behavior at your PC.
Everything works well here, (I'm using Chrome as standard), and the 'popup' disapear as soon as click X in top right corner.
Have you tried another browser, or cleaned up the cookies/cache/temporary files?
If you don't get it to work, and know what file you're searching for, I might find it and paste a direck link for it here in the thread.
