in a new PCB layout:
- move the mouse to an empty part of the design surface
- hit 'a' key. note that there's no blue circle (bug 1)
- move the mouse slightly. note that the blue circle appears.
- hit the '\' key to change trace class
- note that the blue circle doesn't change size (bug 2)
- move the mouse slightly. note that the blue circle changes size.
what's weird is that the trace class change takes effect immediately in the middle of laying a trace, but not before...
