Problem: Why is Kahootz crashing on my IBM Thinkpad?
Type: Hardware

»Description of Solution

Solution: The current version of Kahootz will cause some IBM Thinkpads to crash when opening an Xpression. This problem occurs due to an incompatability between the Thinkpad's ATI video drivers and Kahootz' Intel 3d renderer. You can solve this problem by disabling hardware acceleration in Kahootz. There are two ways you can force Kahootz to run in software mode:. Via the Kahootz Installer: Insert the installation disk and wait for the Installer to launch. The Installer should tell you that Kahootz is already installed. Click on the button marked "Force software mode" then click on the button marked "Test system". When the test is completed; exit the installer. Manually: Locate the "ktz_cf.txt" file in the Kahootz directory on your computer. Open the file in Wordpad and change line 6 to read "Software". Save and close the file. Kahootz should now open safely in software mode. Alternatively; if you are running Kahootz Version 2.0.3 or better; you can solve the problem by using OpenGL as your preferred renderer and still have access to hardware rendering. To do this; locate "ktz_cf.txt" as described above; and change line 6 to read "OpenGL".
