Freezing/Crashing
Over the last couple of days later in the day when I have been working in the builder for more than 6 hours it starts to run really slow and then the current document will freeze. I can still save it and move around within the document using my mouse, but I can't edit or move with the arrow keys. The rest of the documents I have open I can still edit normally. Today when I closed just that document and opened it, it allowed me to edit it. Yesterday it wouldn't even allow me to do that. I then tried to edit the document in another program and it allowed me. After edititing it there and reloading it in the builder it allowed me to edit it.
