interaction with radio buttons

["Johannes Hüsing" <hannes@ruhrau.de>]

Dear all,

using the example of radiobuttons in uptodate 1998-01, I fail to get
the buttons interactive. When using the pdf doc with Acrobat Reader,
the buttons are there but the cursor won't give me the finger when
it hovers over them, nor does clicking have any effect.

Is there anything I fail to observe?

Groetjes
