The best solution in this case is to try generating a crash dump when this
happens, and send it to me. I can analyze the crash dump and hopefully
understand what's going on.
This is how to do that:
1. enable kernel memory dump. Go to the Control Panel, System, choose
Advanced System Settings on the left, go to the Advanced tab, Startup and
recovery settings, in the drop down called "write debugging information"
choose "Kernel memory dump".
2. follow the instructions in this KB to enable crashing your machine
through the keyboard
http://support.microsoft.com/kb/244139 (remember to reboot after you have
changed the registry keys)
3. run your application, when it's hung use the magic key combination to
crash your machine (holding down the right CTRL key and pressing the SCROLL
LOCK key two times).
4. After the machine has crashed and you have rebooted, you will find a
file named "memory.dmp" in c:\windows\. Zip the file and upload it to
5. Let me know when the crash dump is available
Have a nice day
