When remote-ing into a clients machine, if they're using a Mac running Parallels for AutoCAD, if they start the remote session on the Mac side we lose mouse input within AutoCAD. I've been able to replicate this behavior 100% of the time moving between ~6 different machines and configurations. It's always present connecting to a mac, going into parallels and AutoCAD.
If the client starts the remote session from the Windows side, mouse movement in AutoCAD works normally.
