Hi Kimberly, 

Welcome to Box Community and glad to assist!

Are you having trouble with copy paste on each files through box.com? 

If yes, please follow these troubleshooting steps: 

• Updating your browser to the latest version


• Clearing your browser's cache


• Using Box with an alternate browser, computer, or network. 


• Restart your machine. 

Hope it helps! 

I was having this issue in Box Sign. The copy and paste function for Box Sign fields was no longer working as it had previously. After seeing the above suggestions, I updated my Chrome browser and the functionality worked again.
