Copy and paste does not work in QlikView

Copy and paste functions randomly do not work in the QlikView desktop client. 

The issue can occur in any parts on the desktop client;

• Sheet objects
• Expression editor 
• Script editor
• Macro editor 

The issue can occur with any type of copy and paste operation;

• Hot key copy, Ctrl + X
• Hot key paste, Ctrl + C
• Hot key paste, Ctrl + Insert
• Hot key paste, Shift + Insert
• Context menu copy, Right Click > Copy
• Context menu paste, Right Click > Paste

Environment: 

Copy and paste is by default handled by Windows clipboard. QlikView does not have it's own clipboard manager. 

The common reason for failing copy and paste is that an other clipboard manager than Windows default manager is used. The third party clipboard manager for some reason does not handle the copy and paste as expected.

The 3rd part clipboard manager is a common component for remote desktop clients, which need it to handle copy and paste to and from the remote environment. 

Verify if a third party clipboard manager is in use on the client.

Temporary disable or uninstall the clipboard manager to determine if it is interfering. 

The solution to the issue is to either revert to Windows clipboard manager or find an other third party solution that is compatible with QlikView.
