Hi,
sorry for my late answer. I should read this list more regularly.
No apology needed, but thanks.

Puzzling. I've had OOo and the presenter console on my laptop for
quite some time - used to work very smoothly to run on two screens.
However, now I find it hangs completely, and has to be killed with
task manager. It gets part way through the first (dissolve) slide
change, and just stops; totally dead, at which point the primary
screen shows the console elements; the second screen shows the
part-dissolved picture.
The reason for this is a bug triggered by the dissolve effect.
Technical reason: the rectangles are joined into one polygon (with many
loops) that then acts as clip boundary for the part of one slide that is
blended into the other. The rectangles form a regular grid and therefore
have common edges and points with their neighbors.
For the algorithm that joins the rectangles this (the common edges and
points) is a special case that it can not handle very well. The result
is an infinite loop and the hang that you have observed. It happens not
always but often.
Ouch.
I am afraid that there is no simple solution for this, except not using
the dissolve effect.
About the only thing I didn't try was changing the transition type.
Hmmm. The weekend's come and gone, and I used LO (which worked, albeit
with an odd short pause during the dissolve). But I'll see if changing
the transition helps - useful to know for next time.
Thanks.
