>If you look inside the .FRX file of the report (use myreport.frx), you'll see there are several fields, some with variables, some with settings. By saving a copy of the .FRX file without the change, then by making this one change and saving another copy, you can use the SYS(2017, "uniqueId, timestamp", 0, 3) to get the CRC of each row. By comparing the CRCs of each row with SQL SELECT statuements, you can find out which row(s) changed. By looking at them field-by-field you can find out what settings there are that changed.

If I'm not mistaken, there are various places where the .FRX/.FRT and .LBX/.LBT file formats has been documented. Ended up using some of that info to figure out how hack the form files to get things like resizing of page footers in VFP6 (VFP9 has that ability, but VFP6 didn't).
