>Which class in my VFP 9.0 would I change in order to affect my forms ?

If your forms designed with a special label class, then, as Borislav said, you need to just change it in your label class.

If you use VFP base label class in your forms, but use a special form class, then add this line in the form's class Init method.

If you don't use special form's class, then you would have to put this in each form's Init or may be there is another way to do so globally, which I can not think right this moment.

Something like

for each loForm in _screen.Forms
   loForm.SetAll('backcolor',0,'label')
next

in the procedure openining all forms.
