[Plugin: Instapress] Paging issue

Ok i totally love Instapress, but i’ve been going through this paging issue these days.

I have a feed in a page on my blog but the paging doesn’t seem to work well with Firefox or Safari..

But somehow it sometimes works with Chrome (logged in as an admin, dont know if that makes any difference), and i’ve searched and it seemed like some people have the same issue. any suggestions ?

by the way i dont have “Fancybox” plugin installed, although i’ve tried the feed with effects and without same thing.
The only plugin that i have installed other than Instapress is NextGEN Gallery, and i dont think that has anything to do with Instapress.

Thanks in advance
