Hi could I have some help to fix a problem that a user reported on the extension talk
page. The talk page is at
http://www.mediawiki.org/wiki/Extension_talk:CollapsibleVector
and the title is flickering. I am not sure how to fix the problem I was wandering if
someone on here knew how to fix the problem. the source code is at
