Quiz: adding rollover in question-pool question doesn't work?!

Hi!

We want to add a rollover-field (text) in a question integrated in a question-pool.

But the rollover doesn't work in a published course.

The same thing in the same question not used in a question pool but also in that quiz does work.

Has anyone an idea why???

We need that rollover in our question-pool questions..... urgently

Maybe someone had the same problem and knows a solution?

Thanks for your help!!!
