Whenever. open greenfoot, the program starts lagging a ton. Even when I'm not running the actual game itself, even when I'm in script windows, it's lagging to the point of making the game unplayable. No other program on my computer is lagging, and I don't have anything open except a Google Chrome window with two tabs, and of course Greenfoot. I didn't download anything in between today and yesterday when I last opened it, and nothing changed with my computer. It just randomly started lagging to the point of being unbearable. If anyone else has had this issue, or knows how to fix it or make it less intense, it would help so, so much.
