Opera does not fire the onunload event when you reload (since you are not
really unloading, you are reloading). If you need to store the setting
without the unload event firing, you should call the rememberStyle function
immediately after you call the changeStyle function.

I am not entirely sure this is related to the problems you were having with
my script. After selecting English and reloading, my document.cookie is
'LanguageSelection=Eng', but the page is not in English. I have not looked
too hard into how your script works, but this looks like the bug is probably
elsewhere. I am afraid I cannot see offhand where it is.

Is the language setting used server side or client side?

I can see some problems with your script. Most specifically this one:

//  executed when the page unloads - only, don't use it, IE doesn't know
window.onunload = funOnUnloadActions () ;   

That is not true. IE can do onunload. However, you should reference the
function. Instead of referencing it, you are executing it immediately, then
assigning its return value 'undefined' as the event handler (which also
means, by the way, that your onload function does not wait for load before
running, because you make the same mistake there.

What you meant to do was this - no parenthesis:
window.onunload = funOnUnloadActions;

This is not your main problem, but you will be happy to hear that I have
discovered the cause. Opera 9 will not enable a stylesheet if you set
disabled to false, if the stylesheet is an alternate stylesheet, since it
thinks it is already enabled (it is enabled, but alternate). My script works
around this without my realising. It does this by first disabling the
stylesheet, then re-enabling it. Then Opera realises it has to change. This
has no adverse effects on any browser, so it is a very simple, clean fix.
Change this:
objStyleSheets[i].disabled = false ;
to this:
objStyleSheets[i].disabled = true;
objStyleSheets[i].disabled = false;

I will report this bug to Opera.

My problems relate to my using onunload in the demo. Yours are unrelated.
