I used pstricks to insert arrows dynamically connecting different elements
in a slide.
Actually, your comment make me aware of this tikz capability ;)
And it seems also more supported and performant than pstricks!

Thank you very much.

A part from the pstrick/tikz change...
The real problem is the pstricks package, as you abserved.
Even in your minimal test file the error arises.
But removing the pstricks call it disappears!

And also in my real life presentation, removing pstricks, the compilation
completes without error and the
front page has its shaded background, as expected.

Now...I am satisfied to have found a solution...But
I will not be able to sleep (this is not true, obviously :) ) until I
understand what's happening!
Why the combination of pstricks and pgf gives these errors?

It seems more like a clash of some piece of code.
I will investigate, also on the basis of the hints given by other group
members.

Thank you very much

Federico
