CF 8 cfimage => ImageDrawRoundRect is not drawing corner arcs ?

Hello,

I am having an issue with the ImageDrawRoundRect function on two CF 8 servers.   They draw the

rectangles, but they do not round the corners ??   I am using the example from Adobe, and the results

is just a blue rectangle.   I do not know where to go from here, is it a java version, jquery ?   Where

to look.   Any help would be appreciated, as I am at a loss what to look for with this issue.    Server

info. follows.

Thanks, Bob

<!--- This example shows how to draw a square with rounded corners. --->
<!--- Create a 200x200-pixel image. --->
<cfset myImage=ImageNew("",200,200)>
<!--- Set the drawing color for the image to blue. --->
<cfset ImageSetDrawingColor(myImage,"blue")>
<!--- Turn on antialiasing to improve image quality. --->
<cfset ImageSetAntialiasing(myImage,"on")>
<!--- Draw a blue filled square with round corners of arcWidth=10 and arcHeight=2. --->
<cfset ImageDrawRoundRect(myImage,5,5,190,190,"yes",10,2)>
<!--- Display the image in a browser. --->
<cfimage source="#myImage#" action="writeToBrowser">
