Hi @Anonymous
The red cross symbol appears next to the cursor when initiate the "ERASE" command and try to select the object to erase. But during that time the cursor will become a pickbox instead of being as a cursor.
I guess what you are seeing to be a graphic glitch. Try restarting your system and then run AutoCAD and you would see it vanish 🙂
