I've seen the same problem on other (win32?) machines too.

I've also thought about that and yes, I think it's a good idea.
Questions:
- at which layer/protocol to put this pref? probably TCP
- how to name it, suggest: "Try reassembling TCP streams even if TCP checksum is bad"
- which default behaviour to choose (I personally would prefer "Yes", changing the current behaviour, as bad TCP checksums seems to be a common problem. However, other's may disagree)
