In the current bundled version of Envira (1.5.0.6) there is an annoying bug whereby a jump to the top of the page occurs when lightbox navigation is triggered. It basically stops me from using the lightbox feature (unless there is a known hack to fix it?). I noticed in their changelog that this bug was fixed in 1.5.1 released at the end of July and was wondering whether the X version will ever receive this fix?
