The "Arc 45<sup>o</sup>" routing option appears to be incompletely implemented when compared to the "Line 45<sup>o</sup>" routing option.
When routing with Line 45<sup>o</sup> selecting and moving Segments, Connections or Nets, the whole track changes shape but stays connected as a single routed net.
When routing with Arc 45<sup>o</sup> selecting and moving Segments, Connections or Nets, the segment under the cursor disconnects and drags away as a separate segment.
