I have attached herewith a zip with the form & class file (program).
Please check it out.
Run the form & check the alignment of the header caption.
Next, modify the MyHeader.prg & change the alignment & the compile it & run
the form again.
Try this out at least 2 times.
You Should face a problem.
Regards,
Paul
