Yes, I found that IDL doesn't like glass shaders, water, mirrors, or transmapped hair. Admittedly, my computer is 3 years old and only has 512 megs RAM, so I am having difficulty rendering these things in a timely manner. I have taken to deleting IBL lights from my old pz3 files when I try to re-render them with IDL. At least on my computer, IDL and IBL together makes for long render times.
