"tcpdump -w output.log" - file not written

Well, I am trying to output tcpdump output with the -w flag, but it just doesn't write the file, it's almost like it ignores it.
I googled it, and found a few pages with the same problem, but I couldn't find a solution.
Anyone else experienced this?


EDIT:

I found some problems for writing tcp message to a file.
I use Linux RHT6.0, tcpdump3.4 and libpcap0.4. If the type is DLT_EN10MB
and I want to write the tcp message to a file, the message will not be
written to the file unless you input a charater or give other signal. It
seems that "for loop" in function pcap_loop, which is in pcap.c, doesn't
loop untill it receives a signal.  Could anyone tell me why?

What should I do?
