Someone went through the IBO resource usage leaking problem quite a while
back and the few things that weren't being done just right I've corrected.
Grid checkmarks are perhaps one area that hasn't been scrutinized as well as
the rest of the stuff. Perhaps someone out there can use one of those fancy
resource meters to peer into this issue?
