How to prevent form from being resized in Delphi? -

How do I stop changing the size of my form? I do not want to maximize it (which can be toggled through the property editor), but I do not want anyone to be able to drag-sized it. Am I missing something simple, or does it require a little coding?

I am using Delphi 2007.

TForm has the property you need

BorderStyle to bsSingle

Set up so that the form does not appear to be bigger size, and in fact it not big :-)
