A few questions/issues with Orizon and WP 3.8

Hey guys, firstly – love the theme.  I think it just has a few quirks with WP 3.8:

– Whenever I use the Text widget on the right side of the page, a gray background occurs.  Looking at the code, it appears to be a DIV tag from WP overriding the theme.   You can see the problem on http://www.xenoraptor.net

– Sometimes the back end WYSIWYG functions don’t load in the gallery (manage galleries) and post/page editor.  Did a fresh install of WP, worked on default theme, uploaded Orizon, the problem started occurring. 

– Know of an easy way to edit the slider to add a YouTube video?  I know the slider supports it, but my jQuery coding is knowledge is very limited.  Would be much appreciated!
