When I press "save and open next", the page "jump", and the newly opened translation textbox ends up slightly over the top of the screen. It does not happen always, but often enough. Seen at translatewiki.net on Win7 / Chrome 23.0.1271.64 m.
My guess is that this is a timing issue: two AJAX requests are launched, one to save the old translation and hide its box, the other to load the new translation and open its box. The second positions the new box to the top of the screen; if the first finishes later, it scrolls the page up (as a portion of it was hidden) and the new box moves out of the screen.
Together with bug 41464, these two problems are very disruptive when translating lots of short texts.
