Multiple reboots? Why this?
Anyway, the English version doesn’t work for me too.
I'm facing a strange error:
==========
LaTeX Error: File `footnotehyper.sty' not found.
Enter file name:
! Emergency stop.
<read *>
l.36 \usepackage
{amsmath}^^M
*** (cannot \read from terminal in nonstop modes)
==========
Perhaps my LaTeX installation is outdated.
Is anyone able to reproduce the problems with Linux?

Sorry, I cannot verify it for now. But probably you should file a ticket then.

Probably, an example would be nice.

I cannot believe it makes a real difference for users.
As I said already I expect a gain of about 500k if one saves 10% of the image
size.
If anyone wants to do it the way to go is the optimization of the image
sources, IMHO.
Perhaps you can file a ticket for this too?
