i have been trying some stuff.
after turning of kaspersky antivirus network protection the error didnt show up.
all seems to work as intended besides some minor issue with a iso that was not
errorfree apparently. I put my gigabit nic in a networkbridge with firewire , but i dont think that has any effect on the bugging...
so this bug or error is security related to windows xp sp2, caused by a not good
working networkprotection or security. It cannot acces a thread and crashes on the fact that it doesnt get any answer from the thread. it waits forever till it gets an answer and the qwix prog hangs.
Clearly this is a problem in the threading model of the programdesign. I read a lot
about amd and 64bit machines that have problems too. This can also be pin-pointed to the threading use.
xp sp2 firewall related issues can be solved by adding qwix to the allowed program list and if that doesnt work reset the firewall and add it again, it works
hope this helps.
