My Windows 7 makes Half-Life 2 jump up and down? -

My Windows 7 makes Half-Life 2 jump up and down until I put it in Windowed mode. The drivers are up to date, and I can t find an old driver to try. Any suggestions would be appreciated

windows 7 is in beta still, understand that until it is launched and probably a while after there will still be bugs in it, give it some time and eventually the problem will be fixed, you can t expect perfection when dealing with a brand new OS.
