534196 Upgrade Jquery/UI and Fix Fancybox Exit Button

I have a Oscommerce 2.3.1 shop, fairly heavily modified, and lately I've found a few bugs that need fixing, and for some reason I can't figure them out myself. 1.) The Fancybox has been missing the X to exit off the enlarged image. I have looked over the .JS file and both "showCloseButton" & "enableEscapeButton" are set to TRUE, so I'm stumped. 2.) I created and installed a new themeroller theme (jquery-ui-1.8.16) and tried to upgrade Jquery/UI to jquery-ui-1.8.16 but then my "Accordian Categories Box" didn't work and the product image on [login to view URL] was at %100 size, and my "download" image disappeared, so I have re-uploaded "[login to view URL]". I would like to keep it under $10 (I'll owe SL $5 on top of that) This should be a quick fix, and an easy feedback score for you. :)
