Vanguard freezing.
Used the ISBoxer wizard to set up. In the process of creating characters and several Vanguard will stop responding, usually within 5 minutes after launch. Not only do they stop responding, but VGClient.exe (multiple copies) stay in the process list and can't be shut down without a restart. Something else I've noticed is that the window titles will often revert to the default title, though I'm not sure if that's related to the freezing issue.
Let me know if I can include any more info. that will help figure this out.
