I have mostly 0.1 spacing components but I do have a couple of 0.156 two pin headers for power in and out. I had been using ExpressPCB and that design program allowed me to switch off the "snap-to grid" feature temporarily to place those off-grid traces and then switch back on without affecting the rest of the layout.
I am just starting out and ran into this problem. I can not find a work-around in Eagle. Any ideas?
