Hi LyX Experts, I am a new LyX user. I installed Lyx-2.2.1 from the official LyX-2.2.1+qt5-x86_64-cocoa.dmg installer on Mac OSX El Capitan (version 10.11.6). Everything seems to be working OK except for one issue.
I cannot change any of the screen colors. I open LyX->Preferences->Look&Feel->Colors and get a list of colors. Double clicking a color (or clicking Alter... button) brings up color choosing dialog. In this dialog I can pick a color I like. But when I press OK button, both the color-choosing dialog and the Preferences dialog itself disappear without a trace. My choices are not remembered. Am I doing something wrong or it is a bug? Thanks, -- Leo
