I am having a little trouble with some of the G-code Enroute is producing. I'm using Enroute6 but the same thing happens with other versions (3,4,5). My problem is that it keeps trying to make arcs that have zero radius. The problem occurs when ever an offset tool path is generated on an inside corner of an object that has the same radius as the tool. This happens a lot for me because our art designers draw their shapes with the inside corners radiused to match the milling tool so their drawings look like the part that will actually be milled.

Here is an example from a 1/4" tool milling file:
G2 X8.224 Y2.636 I3.435 J3.743
G2 X8.224 Y2.637 I0.0 J0.0
G3 X8.243 Y2.639 I-0.001 J0.133

For the most part I usually can simply delete the offending lines, but I shouldn't have to. Is there a configuration setting that would fix this, or is it a problem that needs changed in the machine driver, (It is one I modified my self) or is it a deeper seeded problem in Enroute itself?
