I'm not sure that there is a bug and it certainly is not here. WMF just
can't be used with the simple watermark interface, WMF requires an open
document. It can be done as easily with a page event and don't tell me
that's difficult to use.
As an extension to your other post you don't have to use the addWatermark(),
it's not suited to what you want to do.
