Stephan Leban Background gradient problem

I am new to Access and had some difficulty with step 10 of Stephan Leban's
background gradient procedure. It turned out that placing the event procedure
in the On Open Form property would not run. When I opened his example form, I
noticed that the event procedures for the background gradient form were in
the On Activate and On Deactivate procedure. When I placed the event in these
areas of my form property everything worked fine.

I am wondering why the gradient would not work on the ON Open procedure as
called for. Does On Activate produce a call before On Open in Access 2007
vs '97 ???

Secondly, is it possible when using a header to have the gradient apply
there as well? Only the detail section of my form has the gradient and not
the Header portion.

Third, is it possible to have the gradient apply to each page of a tabbed
form?

Fourth, is there any way to stop the rectangles from becoming "selected"
when you are doing edits on your form? I tried to bring my fields and
controls to the front, but it does not seem to matter, you still seem to
inadvertently select the gradient rectangles every now and then.
