The screenshot looks fine to me. You can't put ini sections in an mrc file (and expect it to be valid syntax). Also "a lot of RAM" is a subjective unqualified statement. Any syntax highlighter is going to use "more" RAM than the existing editor. I just tested a few script files with ~1500 lines and it raised RAM by ~3mb-- that's a hardly a cause for concern. If anything, you should be worried about CPU, not RAM.
It's within a disabled group... and it only flags items under topics that begin w/ @.
It's also for some reason influencing mIRC's stability... or it in combination with something else. I'm not sure what's the problem. I'll investigate it sometime.
