There are known problems with the System 7.5 Color Picker. The Color Picker is a system dialog that appears in certain applications allowing you to choose colors from an adjustable color wheel. An easy way to see what the Color Picker looks like is to open the Color Control Panel and choose Other from the Highlight pop-up menu. System 7.5 has an enhanced color picker. These enhancements come from the Color Picker extension stored in the Extensions Folder.
When using this enhanced color picker with a Macintosh using two or more monitors, the Color Picker appears on the monitor configured for the highest bit-depth. For example, if you are using a Quadra 800 with a 16-inch display set to 256 colors and a 14-inch display set to millions of colors, the Color Picker shows up on the 14-inch display, since it is capable of showing more colors. The color picker always shows up on the monitor with the highest bit-depth, regardless of which monitor is the startup monitor. The monitor you have set as your startup monitor displays the "Welcome To Macintosh" screen.
Power Macintosh AV Computers
============================
On Power Macintosh AV systems using the HDI-45 port, the Color Picker displays on the monitor attached to the AV card if it is configured for more colors than the built-in video port, even if a monitor is not attached to the AV card. This happens because you can still configure the monitor port from the Monitors Control panel. If you do have the AV Card set to a higher bit-depth, the Color Picker can disappear from view. When the Color Picker displays, however, it is displaying on a non-existent monitor.
Workaround
==========
Step 1
Press Return to close the invisible Color Picker window.
Step 2
Open the monitors Control Panel
Step 3
Adjust the color depth for the "ghost" monitor to 256 colors or less.
A better workaround is to move the monitor from the HDI-45 port to the AV monitor port. This eliminates these types of "ghost" monitor problems.
