I have been making my way through all the tutorials on this site without incident. But when I arrived to the 'Practice' section, I find the white box which lists the game notation (which is typically to the right of the board) is now overlapping part of the board preventing me from moving any pieces there. it begins on file F and completely covers files G and H. I tried reloading the page, signing in and out, but nothing seems to get rid of this annoying white box. I've tried using both Firefox and Explorer browsers on my laptop to no avail. Anyone else come across this issue or can offer a solution?
