Vanishing images when vb clipped

[10west]

[VBA]Set ent3 = Thisdrawing.HandleToObject(eh)
ent3.ClipBoundary clipPoints[/VBA]

Alright, I'm clipping an image and all is fine, I send it a polygon array, and the image is masked. But, unforyunately it dissappears, and I find a spec way out in the middle od nowhere, wheb you put clippingenabled = false, it shows up where I selected it in the very beginning.
Is this an acad bug? 2000 , 2004 , 2007??? has anyone had clipped images, which clip fine manually, just dissappear in vb? I was waiting a while to do this, and now it works, but it doesn't. Even different formats.... thanks

Talking to myself here, fyi, well this one even stumps Autodesk, one of those applicational nitemares, they can't even solve... better see what John Walker is doing, Earth to John, Earth to John...help

Make sure you used for polygon boundary an
array of 2D points and add these lines after:

[vba]ent3.ClippingEnabled = True
ThisDrawing.Regen acActiveViewport[/vba]

I guess where is a mistake there
You need to pass the first point twice!
See how this will be works for you
