one of may colleagues observed that the visibility of some PDF layers may (unreasonably) change when the document restores from Fullscreen mode.
Steps to reproduce:
Open the file ocg-p_example_4.pdf from ocg-p bundle at http://www.ctan.org/pkg/ocg-p . The direct link is http://mirror.ibcp.fr/pub/CTAN/macros/latex/contrib/ocg-p/examples/ocg-p_example_4.pdf .
Press ctrl+L for fullscreen.
Click the header "Grade" in the second table (ocgtabular). The table becomes sorted with respect to grade.
Press Esc to return to the window mode. The table is not sorted now.
Do you have any idea how to change this behavior? Many thanks.
