system.form_status is Changed, when no changes have been made

Hi,

This is my scenario.  (forms  10.1.2.3.0)-- Custom form to be used in Oracle applications

1) open multi record Data block - table 1  (with limited fields displayed) - No update/insert/delete allowed

2) Run a query

3) Hit push button to open new canvas/data block with table 1 -- all fields for chosen record.

4) Only one field of many is updatable.

5) Make no changes, do not navigate to updatable field

6) close canvas and return to original canvas.

7) When navigate to another record and hit push button: Receive Message - Do you want to save your changes?

     system.form_status =  changed, even though no changes were made.
