Well, I've continued to experiment. Here are the files I've updated:
Files updated: RichText.pm typemap typemap.xsp typemap.svn-base typemap.xsp.svn-base RichTextPrinting.xsp Not RichText.xs because I used Mark's file. I'm still getting the same (or a very similar) dump. I guess what I'm not clear about is the relationship between the files, ie which ones feed one another. Many of them have "do not update ...." or something which is helpful, but others appear identical and I assume one is copied and one is original. Thanks and regards Steve
