We have updated to Windows 10. I noticed a bit of difficulty getting Civil 3d as the default program for project files. After constant crashes and using "control alt delete/task manager" numerous times it has occurred to me that when I do end the task that the Icon the files are running in is the Regular red AutoCAD Icon not the Blue Civil 3D Imperial Icon. Is there a possibility that is an issue? We have 4 Civil 3d users. and Civil 3d is crashing on us much more than just an occasional file that needed auditing like before Windows 10.
