Hi Michael and Peter, Apparently the problem is (actually was) something to do with blowing the limit of a stack. The developer I spoke to couldn't remember when the fix had gone in - it might have been in 2006GB, but if not then it should be in an FME 2007 beta.
If you try the 2007 beta version and the problem still exists then definitely send the info to [EMAIL PROTECTED] and we'll look into it.
