Yes.

Either

	1) use a snapshot length, in the capture dialog box, less than
	   or equal to the MTU of the device on which you're capturing

or

	2) use the current CVS snapshot of libpcap (tarballs of the
	   snapshot are made every night, and can be downloaded from the
	   tcpdump.org home page), rather than 0.5.2.
