Vlad,
I don't remember VFP3 behaviour or even if headeheight existed there or not.
If we're talking about VFP5.00 and later then I never encountered problem in setting headerheight to 0. It completely hides the header.
Also putting say a container in front of header in VFP5.00 and up works too.
I never saw top-left square insisting to stay there either.

>Ceting, in more earlier versions of VFP when setting HeaderHeight to 0, it does not hide headers completely. I remember, once this was known and sad problem in my application. Now setting headerHeight to 0 and AllowHeaderSizing to .F. allow to get rid of headers, but not completely - my VFP6SP5 still try to show a top-left square box as a single line...

>Nadya, Grid header draw self always above other VFP controls. You can hide grid header or put something above it by putting another Window inside of the form (DEFINE WINDOW ... IN WINDOW), but this also has many other problems, in particular, it is impossible to get that window fire events in a modal form.
