If you are experiencing an issue with a particular software then first try closing the software completely and reopen it to see if the issue goes away.
If you are experiencing an issue with a piece of hardware such as a PC, Laptop or Tablet then always close all of your applications and reboot the unit to see if the issue goes away.
If none of these work then please place a support ticket with as much detail as possible for us to help troubleshoot.
Thank you,
