I'm using transposh on another project and it's going quite well besides this little error. I'm using a plugin to implement a slideshow Portfolio Slideshow and when using transposh it seems to translate down the DOM until it hits the slideshow and then stops, not translating any further. I've tried another slideshow plugin and got the same results.
You can view it on the development site here.. and to get past the curtain I'm sending you the credentials via your contact form at transposh.org
The language toggle is in the top left :-)
