Hi
I am currently using 5.2 pro, and am having the same issues although consistently.
I have created an overview page where when the item is clicked it action is set to jump to another canvas.
Currently I have about 67 actions and only 12 of them function correctly.
The others all go to the same canvas, although it is the incorrect canvas.
The canvas name in the action is correct, it just goes to the incorrect canvas.
just upgraded to snow leopard with correction in the issue.
Thanks for the attention!!
