https://forums.autodesk.com/t5/autocad-forum/curser-turns-into-a-no-entry-symbol-problem-solved-filedia/m-p/5641024#M328071 <P>Whilst trying to open up AutoCAD files using the Open function through the AutoCAD interface the usual open dialogue box does not appear and when I try and select something else the mouse curser turns into a No Entry symbol (red circle with diagonal red line through it) even pressing Esc does nothing and I am unable to close the program without ending the task in task manager. I have restarted my PC and tried again and it is still the same.</P> Tue, 19 May 2015 02:42:47 GMT Anonymous 2015-05-19T02:42:47Z
