Using Altium Designer 2009 to route out my PCB, I accidentally hit a unknown key combination on my keyboard and now all un-routed nets show up with two double slashes. Moreover, the center of each component pad shows up with a white dot. After connecting a trace between the pads, the un-routed net does not disappear.
What could I have done, and how do I get rid of this behavior?
Solved: I used the "Reset error markers command" accessed from a context-sensitive pop-up menu. This seemed to reset everything and got rid of all of the strange slash marks.
