Figure A and B is just my example to illustrate this problem, marquee A and B, are different to select the whole circuit, then de-select the bottom right hand corner part, such deselect put some only partially contained in the Net A zone or area B deselected. As shown Net C. In addition, xDX Designer does not find de-select menu, if you hold down ctrl key marquee, will be like, as shown above, only de-select Net, component remains in the selected state.
Similarly, if do not intersect with A when selecting the bottom section of B, will put some portion of Area A, Area B section in Net deselected. As shown Net D.
successive use of Ctrl should select then de-select is possible, but now the phenomenon is very confused, like I said, just de-select Net, component remains in the selected state.
Also, if you can not use ctrl key, but can use the Shift key to achieve the effect I want, many other software are doing.
Thank you!
