Copy and paste
We use SC extensively—every day, all day—and it’s become an essential tool in our workflow. Unfortunately, the copy-and-paste functionality has recently started causing significant issues. While this problem is relatively new for us, discussions in the forums suggest it may have been a long-standing concern.
Is there a plan to address this issue? Or are we facing the possibility that SC may no longer meet our needs?

While I can give you no guarantees (and do not work for Connectwise, 26.5.1.9678 was released this past week; I would recommend making a snapshot of your ScreenConnect server (or other backup) and then upgrading and testing with the newer version.
What's the cause of the delay on resolution for the copy paste functionality between the host and client?
Could you remind me how to trigger and would enabling the debug / extra options for SC program on machines used for troubleshooting help?
