Symbol Selection/Grabbing Region
The symbol selection/grabbing region on editor drawn systems can be in error. Most of the time things will be ok with this release but try and draw the symbol symmetrically, making the first point of the first line at a point of symmetry. e.g. Suppose a rectangle is drawn. Instead of starting at a corner and using one line for a side, start in the middle and draw a line to the end, then draw the other bit of the line for that side. The rest is drawn as normal signal lines.
