>>I'm actually surprised you get the exact error, and get as far, as you do <s>. Do you have an error handler that could be masking this earlier error?

This issue is fixed in more recent builds, and I can't repro your problem in a recent build, no matter what Builder I use <s>.

Thanks for the reply,
I have an error handler, but it doesn't appear. Its only coming from the report builder error handler. Modifying & Saving, its ok only when I select the New button....
