I changed the packetsize to 4096 and all of a sudden files that wouldn't send (timed out), or got stuck will send now!

There was still one file that still wouldnt send. Set packetsize to 2048 and now it works too!!
Uptill now, i haven't come across a file that wouldnt send now, but we'll see what happens..

what's with this packetsize???
Why doesn't it work right away ???
