problems quimaker using Windows XP and Opera browser

Hi,

I have the following problem. My quiz won't start, just the "wheel in spinning" the first time I use it with Win XP and Opera. If I start the quiz using a different browser it works fine, also if I open it using Opera after I opened at least once with IE or Firefox, it works. It just won't open when started for the first time using Opera browser.

I checked on the PCs wiht Win XP and Opera and have the same results. I embed my quizzes into the Presenter. Other slides open just fine, quizzes don't.

Is there a solution for this?
