Steps I took that resulted in the problem:
Top 2 pins have lump when bendpoint is horizontal with pin, bottom 2 don't but the bendpoint isn't horizontal with pin.
If you add a bendpoint very close to the centre of a part's pin that is joined with a 45º trace that is thicker than std(24mil), the trace kicksout a protruding lump.
Add 2 resistors.
Join with a trace that is angled approx 45º
Made trace thicker than 24mil.
Click on trace and slide a bendpoint close to the resistor leg pin so that's it's horizontal to the pin but one grid-snap to the side.
I saved the sketch, closed it and restarted, but it's still there.
What I expected should have happened instead:
No lump kickout on trace.
My version of Fritzing and my operating system:
Win7 64 SP1
