I am working on a project in ArcMap 10.3 that requires a lot of repetitive operations. I also recently updated to Windows 10. For most every operation the cursor wheel just goes around and around while the words "ArcMap not responding" appears on top. Do you have any idea why it does not "respond" any quicker? It appears from the threads on Google that this has been a problem for quite some time. None of the things that they have suggested have helped.
