RE: [GD-Windows] os version

[Brian S. <bs...@mi...>]

The official stance is you can't disable it, so don't even try.  =
Unofficially, I know you can block it in some cases, but I still don't =
think you can disable it in all cases on 2000/XP.  And your users don't =
really want you to disable it anyway.  They want you to deactivate the =
windows key so they don't hit that in a game, but people like to be able =
to alt-tab away if they need to.

Possibly Quake tears down everything when it loses focus - releases all =
textures and shuts down GL - and then starts everything back up when it =
gets focus back.  That seems like a safe approach, at least. =20

They released the source to Quake 1, so you could look there...
