Scratch

I opened up Scratch earlier today (or maybe it was yesterday...) and all of the text and projects and stuff were smaller. I could still see stuff as clearly as I could, but the text got smaller, project boxes on the front page, etc. So, I clicked on a project I wanted to see and the project box was smaller. It was cut off on the bottem, left and right sides, cutting off words and stuff on those sides and even cutting off the green flag and the red stop sign. It's never happened to me before.
Also, I went into the project creator thingy and I started drawing with my tablet. Well, I tried. It wouldn't let me draw, not even if I pressed the pen down really hard. So I unplugged it from my computer and plugged it back in, which was part of the instructions that came with my tablet. A few minutes before, I was drawing on an art program I have called ArtRage, and my tablet sensed every pen touch, even the lightest touch, as it always did.
Has anyone else experienced these problems? Or does anybody have a way to fix this?
