frames compatibility

Hey all, I'm working on a project and considering splitting up the pages into frames. I'm mostly wondering are the frames implementations across browsers relatively similar? I'm thinking that I'd use 3 frames split like this: 1. Filelist of documents to edit 2. A document editor 3. A help index Luckily I don't think I even need to share my session between the frames, but I do want to use a session for the document editor. Has anyone done anything similar to this? What compatibility issues are there? I searched MARC and didn't find much of anything... only 5-7 problems reported for frames/KHTML frames/MSIE and frames/Mozilla. Are frames really that stable?
