As far as I can see, in some places where Moodle lets you specify a start an close date for something (in particular for a quiz), there is nothing to stop you entering a close date that is before the open date.
This is a bug, isn't it?
Even if it is. Should I fix it on the 1.6 branch. Probably not. Unless anyone disagrees, I'll just check a fix into HEAD.
