- soled bug in Gerber Editor: the '0' aperture (the region aperture) had no size which created errors. Made the size to be zero.

- solved bug in editors: the canvas selection shape was not deleted on mouse release if the grid snap was OFF
- solved bug in Excellon Editor: when selecting a drill hole on canvas the selected row in the Tools Table was not the correct onw but the next highest row
