As of a few months now,(April 05) I cannot enter text into new messages using my PC laptop (Win10). When I try, the cursor jumps around, text does not stay, I cannot delete or start anew. If I access CC on my Android tablet, it works fine. Its just a pain to have to switch that way.
Thank you for reaching out to the Community! It do apologize for your experience, but it sounds like their is something wrong with your touch pad on your computer. Have you tried using a computer with a mouse instead of a touch pad for troubleshooting? Thank you.
