<p>> You can lock an object by using the static method
"Object.Lock". <br>
> There is no "Lock" method in the DrawingArea class."</p>
<p>I don't understand the above. Quoting from <a

<p>Since the above (later on in that web page) refers to a Button as
an Object , I think that a Drawing Area is an object and therefore
Lock & Unlock should be methods available to it.<br>
Also, the compiler does not object to e.g. DesktopDrawingArea (a
Drawing Area) being used with Lock as in DesktopDrawingArea.Lock.</p>
<p>I do try to follow Netiquette (in <a moz-do-not-send="true"
href="http://gambaswiki.org/wiki/doc/netiquette">http://gambaswiki.org/wiki/doc/netiquette</a>),
so please tell me <u>specifically </u>where I go wrong. <br>
