Dear Thomas,

thanks for the hint. There are tow problems though. First, I can't program JavaScript. For some extra features we have to ask a programmer who is not part of our lab to program them. Second, that would work with one screen only, right? We use the custom item feature for our complete experiments. How would I use this popup feature in such a setting?

I imagine one could start a popup on the first screen and then program everything else within this popup windows with div tags. INstead of skipping to the next custom item one would then have only one item with different areas being visible on different times.

Blair, would that work? And would that be less complicated than to just get rid of the back border or to make it like only one pixel thick?

Thanks in advance!
Rene
