Yes, this is by design. Just re-set the grandchild's buffering in the data environment.

Tai, try it without the () on the GO (nRecno) line.

Also, is there a tableupdate in your Refresh code? That would change the negative recno to a positive one. Check the actual recno() with your message boxes or with debug.
