I think this is a problem with TCP in blitz. It will hang unless their is a response i beleive. I used UDP with reliable packets, but i also used the RottNet network library from the toolbox. You can send packets marked reliable, which will definetly be delieved. Problem is, you'll have to sort out the order in which they get received, as they sometimes arrive out of place.
No big deal though, just timestamp each packet with Millisecs() :o)
