Can't fill any text field...

Hello

I'm just trying out Articulate QizMaker '09. I've installed the trial version.

When I try to create a new question, I can't fill any field. When I do a left click on a field (to create the question for instance), it doesn't work. I can't fill any answers neither.

Is it a trial limitation ?

I'm using V3.31103.112.

I've installed only QuizMaker. Should I have to install any other component of Studio '09 ?

Thanks for your answers.
