4 out of 5 nets routed

Spurious unrouted connections in BB view

Steps I took that resulted in the problem: Started Fritzing. Switch to BB view Added Arduino Uno Added two ceramic capacitors Plugged first capacitor into two unconnected locations on the board - status bar says: no connections to route Plugged second capacitor into pin 8 and 9 of Arduino headers - 0 of 2 nets routed - two connections still to be routed Removed second capacitor and dragged wires from arduino 8 and 9 to capacitor - routing completed. … What I expected should have happened…
