For a while now, the folding markers for many methods seem to be off-by-one. I haven't yet figured out exactly what causes this, since I figured it would probably get noticed and fixed in a few days anyhow. I think it's been doing this for at least a month, and I've finally gotten motivated enough to bring it up. Here's a screen shot - notice the collapse icon is in the method body, not the signature:
I thought I detected a paettern where it happened after an Implements or Handles keyword, but that wasn't consistent. Removing the comment block above didn't correct it, either. I'll try to track down more definitive info on what causes it and what doesn't.
