Disabling the close button on a form

[kleaves]

I have a form which I want to disable the close button. On the properties of the form I set Close Button option to 'NO'. When I open the form the form close button is disable, but as soon as I maximse this screen, the close button becomes enabled again. Any Ideas as to why this is happening and how I can disable this button comlpetely on this form?

The search function on the site does really work. This question has been asked over and over, so there are plenty of posts on this topic. For example when I placed "Disable X Button" into the search criteria, I got:
