I don't know how NDIS handles outgoing packets, so I don't know whether an NDIS driver has to do something special to ensure that outgoing packets are seen by code that taps into NDIS - such as WinPcap.
This question is probably best asked of the WinPcap developers, as it's extremely unlikely to have anything to do with Ethereal or what particular version of Ethereal you're using. 

Try downloading WinDump:

	http://windump.polito.it/
and try capturing with it, and see if it has the same problem (which I strongly suspect it will). 

If so, it is, in fact, a WinPcap problem; see

	http://winpcap.polito.it/contact.htm

for information on how to report WinPcap problems.
