(This may or may not be related to this.) In my experience, most sites on the internet are buggy to some degree or another. In particular, almost *all* of them are sensitive to what should be minor variations in the client configuration. The closer you are to the authors standard configuration (almost inevitably a slightly dated version of IE on a similarly dated version of 32bit Windows in their out of the box configuration with the server on the local lan), the more likely things are to work for you. Three of your own suggested fixes are "Run something more like what the author runs": > Run the Linux32 version -- Usually works well. > Run the native 32bit version on an i386 (athlon-xp) or > Run the 32bit version under emulation on amd64. (in a jail) > (Both the real and 'emulated' i386 work error-free.) So, you might try: 1) Creating a new users with all software configured to it's default state. 2) Remove any system-level config info for the relevant software. 3) Reinstall said software. If you're compiling from source, reset the config to the defaults. As to the other fixes, they may be good advice, but aren't things that can be done in the FreeBSD source tree. > >Fix: > Some sites should be aware of this and perhaps write better scripts.
