I am running Internet explorer (9.0.8112.16421) on a windows 7 computer and yesterday it was working just fine, but today I cannot see any projects. The entire screen except for the bottom “more projects by this person” and top “scratch, create, explore…” comes up blank. I can click things on the screen (that I can't see) because the mouse pointer turns into a glove when I'm on the invisible link, but I cant see any projects.
