Hello, Again Smartbuilder Team, 
Is there any way to clear Recent Colors while working on a lesson?  I find that at times I use colors as I start working on a project then as I choose more and the list grows a bit, the previously used colors are gone.  Even after I use the eyedropper to pick the color again it's not added to the list.  Hopefully, this all makes sense.  Basically, I'd love to find a way to reset my recently used colors.  
Thanks! 
Scott

Hi Scott,
That sounds like a bug. Usually a color should be added to Recent Colors unless it's already in Recent Colors. I would start a support chat so we can look at it together to gather some more info.

But a workaround is to close SmartBuilder, launch it in Safe Mode, and then relaunch normally. This should clear the Recent Colors.
