Thanks Ruben. Yeah, it is a toughie - I had to rename several classes when it came to integrating our UBB and ImageFolioPro installation, the same class names abounded...

I can't for the life of me think what's conflicting, but thanks for the tip, I'll try deleting a section at a time and see what gives.

I'll post here again when I narrow it down. Wish me luck..!
