Hi,

I have implamented  possibility to digitize holes into existing polygons 
(donuts),
and it seems to be working well:

http://dev.openlayers.org/sandbox/jachym/donuts2/examples/editingtoolbar.html

howto:
1) draw polygon
2) draw 'hole' into it

It works in Firefox and Opera and kind-of-works in IE.

In IE, you draw the polygon and when you try to draw the hole, the
polygon jumps from the original location (the difference and direction
corresponds with the difference between first point of polygon and first
point of hole). Than it moves around the map, while you are dragging the
mouse. When you finish the hole, it jumps back and everything
looks fine again.

Is it possible, that there is bug in OpenLayers.Renderer.VML? I was not
able to trek down the code.

Thanks

Jachym
