Change Tab Order and Docking


Just wondering if anybody has seen errors result from changing tab orders on a form or repositioning and docking panels?

I made this change to an existing customization.
Moved a couple fields and changed the tab order on AP entry header form. I undocked Misc Charge (APHead) and redocked it, next to the AP Header panel, on the RH side.

Later I was told it started producing errors after a few records had been processed, but I don't have details.
Just starting to test now.

Thanks in advance
