When using RealVNC on Windows, I can sometimes cut and paste from VNC into Window's apps, and sometimes it just stops working. How can I get it reset so it works again? I've tried restarting VNC, but that doesn't do it.
If you have access, check global permissions on the VNC Server Options > Users & Permissions page. Has VNC Server been configured to prevent you copying and pasting? If you have access, check permissions for the user you are registered as on the VNC Server Options > Users & Permissions page.
Transferring a file Just open VNC Viewer and, on the machine you are controlling, right-click VNC Server. You will find the icon in the system tray. Select File Transfer from the menu.

Many times you must have observed that clipboard operations like copy/cut and paste suddenly stops workings with the vncviewer. The main reason for this there is a program called as vncconfig responsible for these clipboard transfers. Some times the program may get closed because of some bug in vnc or some other reasons like you closed that window.
To get those clipboard operations back you need to run the program "vncconfig &".
After this your clipboard actions should work fine with out any problems.
Run "vncconfig &" on the client.
