Buildin Forumrunner issue

[Stefan118]

I have the known issue of IE10 and forumrunner (Enter key does not work in IE10).

I found the solution on this page:
http://www.vbulletin.com/forum/forum/vbulletin-4/vbulletin-4-questions-problems-and-troubleshooting/400766-common-issues-latest-release-4-2-1?p=3963696#post3963696

Please help!
What, Where and How do I change the Forumrunner part of that threat?
Are they talking about a template? A file? How do I change the plugin???
