- Random guidelines appearing when zoomed all the way in ---

Zoomed in as far as one can zoom there are three guidelines appearing. Look at the attached images for proof. The problem is that when snapping objects to the grid, the object is not snapping to the correct guideline and I'm getting a gap between model elements. You'll see that the adjacent guidelines are only one guideline each. The size of the gap is incredibly tiny, but for meshes being pushed to UDK, it's important that they do not exist. To move the mesh such a small amount is a bit tedious and I'm afraid that if I don't correct for these slight discrepancies they will be cumulative producing more spacing errors as I continue to add to the structure of my developing mesh.

%%%Please post a blend file which has these strange artifacts.%%%

%%%The problem is getting worse, and now there are 3 horizontal guidelines.%%%

%%%developer note: this looks like a precision issue with drawgrid_draw when called from drawgrid with unit->system set.
'dx' gets to be around 893398.%%%

%%%note that I think we would need to use a different method of drawing grid-lines to stop this error from happening.%%%

%%%I'm guessing that is noted for the coders, but from my perspective while the error is minuscule (my calculation being 3/1000th of a millimeter) I'm afraid that its cumulative effect will add up to ultimately cause more serious distance and snap issues as I progress. %%%
