Validation error...

Hello,

Firstly, I'd like to say I think this is an awesome module, arguably the best one out there. However, I seem to have a problem with it when users are logged in.

When the visitor is not logged in, the translation seems to work fine.

However, when logged in, changing the language seems to be fine (e.g. to spanish) but then when I move around the site, it shows the user login box indicating that i've been logged out. Stranger still, when I go to change the language back to English (or anything else), the user login box disappears and the username reappears (indicating I am still logged in), but I get the following error:

"Validation error, please try again. If this error persists, please contact the site administrator."

I can't seem to clear the problem until i logout the user and log back in again.

I'm stumped. I've got biblio module installed as well, but that's it I think (for non-core modules).

Am I missing something obvious? I'm running gtrans 5-x-1.3 with Firefox on a Mac

Thanks a load,

Peashooter
