If you are using a Huion Tablet in Windows and are using Google Chrome, and you can use your tablet to click buttons on the lesson space but you cannot write, then do the following:

  1. Re-install your Huion Drivers. Uninstall the current driver, then install the latest updated driver corresponding to your tablet (found here), and restart your computer.
  2. Open your Huion Pen Tablet Administrator. Untick the radio box that says "Support TabletPC" as seen in the image below:

Alternatively, a quick fix is to switch to Firefox since there haven't been any reports of this problem occurring in this browser.
