This drove me crazy for a bit until I found out what was happening.
I set my ratsnest colors for a few specific nets to colors I wanted. Every now and then I would notice they had changed back to the default color. I noticed that it was happening after I was using the "highlight" command to cross probe with Capture while placing components (functionality of this leaves a LOT to be desired........ but that is for another post). In order to clear the highlighted parts "clutter" (since picking another part does not dehighlight the previous part) I would click "Dehighlight" then select "All". This would clear previously highlighted parts, but also remove the colors I had assigned to specific rats.
Why??
Is this a bug or me............. again.............?
