Copyclip/copybase and pasteclip in AutoCAD Mechanical 2015

[nstalker]

copyclip/copybase and pasteclip in AutoCAD Mechanical 2015 causing fatal errors frequently

not sure why this is happening.  It happens when I pasteclip into another drawing, be it existing or new.  Happens with different drawings and objects too.

Anyone else experiencing this?

I'm having to open ACAD 2014 to get the job done.

Have you tried to launch AutoCAD Mechanical (ACADM) as Core (or Vanilla) AutoCAD (Start > All Programs > Autodesk > ACADM 2015 > AutoCAD 2015)?  You mentioned that you have to open ACAD 2014, are you using Mechanical or just Core AutoCAD 2014?

I haven't tried launching AutoCAD vanilla because I want to work in Mechanical.  It has features that vanilla doesn't have that have become a regular part of my workflow.  FYI I just had this problem again this morning.
