When editing a color from the Property Editor the color picker dialog overlaps the Windows taskbar. This creates a problem if I click away (usually to copy a color in hex format) and then click back. The Hex value is now hidden by the task bar. It seems like there is another dialog that has that problem as well. If I find it again I will update this post.
