https://forums.autodesk.com/t5/autocad-forum/i-cannot-deselect-multiple-lines-at-a-time-using-shift/m-p/5882849#M305807 <P>It has the program microvellum installed, but otherwise is vanilla. It happens in all drawings. I can get a video of it, but there isn't much to see. It looks exactly like a regular shift-select except only one line or object deselects at a time. What weird is group selection is on, but it deselects lines from within the group. Here is a screenshot of my settings:&nbsp;<A href="http://imgur.com/7u5A7B9&nbsp;" target="_blank">http://imgur.com/7u5A7B9&nbsp;</A></P> <DIV id="ab84982d-cad8-490b-b2d2-e7b3710407c2" class="myscreencast-iframe iframe-container active-myscreencast"><IFRAME src="https://screencast.autodesk.com/Embed/Timeline/ab84982d-cad8-490b-b2d2-e7b3710407c2" width="640" height="650" frameborder="0" scrolling="no" allowfullscreen="allowfullscreen" webkitallowfullscreen="webkitallowfullscreen" style="display: inline;"></IFRAME></DIV> Wed, 28 Oct 2015 21:10:04 GMT Anonymous 2015-10-28T21:10:04Z
