We are running theme Showcase and all was well with 1.0.13
I saw that there was an update available, so I updated the Showcase theme to 1.0.14 and the slide show on top of the home page quit working.
I tried creating a new home page, creating new projects, etc. and nothing would fix it.
So I downloaded 1.0.13 and uploaded the files manually via FTP overwriting the 1.0.14 files and everything went back to working.
Something in 1.0.14 is broken.
