I just installed Casino 3D. All of the buttons are misaligned, meaning that the "hot spot" to click the button is offset to the right of the actual button.
This is not an issue with your monitor but rather with the graphics adapter in your machine. Be sure you are using the latest drivers. If it is Nvidia or ATI be sure to download fresh new drivers from their sites as opposed to using the ones that came with your machine if you had a graphics card installed at the time your computer was built.
