latest updates for Half-Life.

Q. I cannot use OpenGL when I have two monitors installed. How can I fix it?

Under Windows 9x/ME, this is a known issue with the Microsoft OpenGL driver and systems with more
than one monitor, whether TwinView or separate cards. The only way to get round it currently is to
disable one of the monitors.

Under Windows 2000 on TwinView cards, full screen OpenGL will only work on the primary monitor
and then only if the secondary monitor is disabled.

Under Windows 2000 on TwinView cards, windowed OpenGL will work on both monitors.

Under Windows 2000 on separate cards, full screen OpenGL only works on the primary card and then
only if the secondary card is disabled. However, if the two graphics cards are both based on NVIDIA
chipsets that use the Detonator drivers, full screen OpenGL will work on both cards.

Under Windows 2000 on separate cards, windowed OpenGL usually only works on the primary card.
However, if the two graphics cards have the same NVIDIA chipset (e.g. they are both TNT2 cards), the
'Enable advanced multiple monitors' option is available which will allow windowed OpenGL to work on
both cards.

In all situations, if a 3D application is designed to work on the primary monitor only then it will not
launch on the secondary monitor nor will it operate if dragged over to the secondary monitor (when run
in windowed mode).

Q. I get two monitors detected when I only use one. How can I disable TwinView?
Create a binary registry key called 'TwinViewDisabled' to the value 1 in the following registry subkey:
HKEY_LOCAL_MACHINE\Software\NVIDIA Corporation\Global\System
and TwinView should be disabled, preventing a second monitor from being detected.
