By modify icons I mean the double headed arrows on the sides and corners of the selected part (the diode in this case) that you can then select and drag and they will scale or move the part. I just tried this using object transform but the same thing happens. When saved and moved in to the file that fritzing is using the icon is the correct size, but it is aligned half way between the grid lines (as it is in inkscape with both this one and the one that works correctly) and the connector pins aren't there any more so clicking on the end of a wire won't make a connection, I expect there is something relatively simple that I'm not doing but I don't know what it is.
