This is actually a problem with At Ease 2.0 in both Workgroups and the Non-Workgroups version when setting monitor bit depth.
There are two issues:
* The options will include "thousands" and "millions of colors" and other choices, whether your video card supports it or not.
* The 'hot spot' on the pull down selection is mapped to the wrong spot. Clicking and holding on the actual name (to the left of the triangle) will display all the available options for color choices. You can then set the color selection for that particular application.
