Problem with Scamper in a ProjectLink

Hi everybody,

I just got a ProjectLink inside the CobaltWorld working, showing an instance of
Scamper. Everything is fine so far, except clicking on web links has no effect.
Instead, I can mark a selection within a links text.

I want to try to make it work, but I don't know where to look this up. My
installation of Scamper has no such problem inside a 2D squeak world.

Any suggestions?

Greetz...
