Why aren't signatures aren't working on my touch screen device

Issue: 

When using Google Chrome on Microsoft Surface tablets, some users aren't able to add digital signatures (in the Controlled Substances module) using the touchscreen. 

Solution #1: 

  1. In Chrome, type in chrome://flags in the address bar. 
  2. Type "Touch Events API" in the Search flags field. 
  3. Enable it and relaunch Chrome. 

Solution #2: 

  1. Find the shortcut icon to Google Chrome on the desktop / home screen.
  2. Right click the icon and select Properties > Shortcut
  3. Paste this into the target (including the quotes): "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --touch-events 
  4. Click Apply / OK
  5. Launch Chrome and see if the signatures work.
