Well, next time they click the "rebuild grid" button, just build a new grid. If the previous grid may be reused while form is still in use, keep it; if not, kill it.

Ah, forgot the best part: load time will be the saem, since you start with just one grid. Also, building a new one shouldn't be slower than rebuilding the old one.
