I'm using Viper's Video Quicktags to embed videos on a client's WordPress site and I've noticed that, strangely enough, the video embeds are affecting the way text is being shown, but only in Safari.
If you see on this page: http://www.studiojona.nl/wordpress/work/rampreizen (with Vimeo and YouTube embedded) compared to http://www.studiojona.nl/wordpress/work/greenchoice/, the text in the right-hand column is noticeably a different colour and a different weight in the first instance.
I'm assuming its an issue with some open tags somewhere, because as soon as I remove the video embeds, the page goes back to normal.
If anyone could shed some light on my situation, that'd be great, it's reasonably urgent.
