[trunk] Cannot select any element on pages other than the first

Setup: SVN rev. 4595; Qt Lib 4.7.3; Ubuntu 11.04

Steps:

1) load or create a score with more than 1 single page
2) click on an element whatsoever (note, text, frame, ...) in any page other than the first

Result: the element is not selected.

Note: priority set to critical as it greatly limits the program functionality.
