Well, mysteries are there anyway. Remember I was always complaining about a hyphen pasted as soon as I opened TG and typed something? That mysteriously disappeared (luckily), but yesterday I was doing some animation work in the animation panel, and as soon as I typed something the hyphen was there again.
I also had a little issue with the animation panel disappearing itself. It was on the taskbar, but when clicking it to the front, it never appeared. Looked like it was offscreen somewhere. So I had to delete it and reopen. Nothing major, but still a mystery.
