Hi
Are you using pageframes with perhaps some sort of search facility, to look up records already entered.
Similar problem for me where page 2 (patient details) was the entry page and page 4 (patient Invoices) was a Search page.
Some objects on page 2 where calling the afterrowcolchange event of the search grid on page 4 (Why I Dont Know) after a new record had been added to the patient file.
This call to page 4 caused the record pointer to move in the patient detail file away from the added record.

I finally trapped this, using the coverage profiler, noticing events and methods getting coverage when they should not be.

I was using all the usual Buffering, private Datasession, etc

Hope this helps
