8O ops: :x :?
Finally figured out why ks3 tests have been attempting to load links in firefox. We have been using a variation on the internet control script posted a while back on edugeek. It changes ACLs on files to stop kids running Ie and firefox. However the tests use mshtml.dll to render their internal webpages, so here's a hint: Make sure the pupils have access to this file when they attempt the tests!
Can't believe it has taken me this long to tie this one down! LOL. It's too hot, time for a cold beer!
