I just came across a problem that isn't so bad, but I would like for it to be fixed. I was making a project earlier and suddenly, I couldn't start the project or move/edit scripts! I could still save the project, move the scrollbar (the scripts move), make costumes, edit sounds, but I couldn't really do anything. After I went to the costume tab, I clicked back to scripts and the whole workspace disappeared! Here's a screenshot;

It looks like a Sprite isn't selected either. Since nothing is selected, Scratch has no scripts to load.
