I had the exact same problem, and after much digging found a patch from Peter Stamfest that solves it. The patch, along with an explanation, can be found at http://lists.w3.org/Archives/Public/www-lib/2000JulSep/0241.html > For me, the bandaid solution was to modify the implementation of > HTHost_getReadNet() with this ugly hack: > > PUBLIC HTNet * HTHost_getReadNet(HTHost * host) > { > #ifdef WIN32 /* !!!yikes!!! */ > if (IsBadReadPtr(host->pipeline, 1)) > return NULL; > #endif > return host ?

This is much neater than using the Win32 IsBadReadPtr function later on in the game. Regards, Tim Serong -- tim.serong@conceiva.com http://www.conceiva.com
