Browser Updates and digital signatures (electronic signing) in eVetPractice

 Per recent updates from various browser developers, changes will need to be made to the setup and/or configuration of most browsers to allow touch screen signing electronically to work properly in eVetPractice.  The 3 browsers that will be discussed in this article are Microsoft Edge, Mozilla Firefox, and Google Chrome.


For Microsoft Edge, these are the steps that would need to be done.  Please note this is for the "classic" Edge browser.  If you have the new Chromium-based Edge, please see the steps below for Chrome 78 or higher.

1.  Open a new page in Edge.

2.  Enter about:flags in Edge's address bar.

3.  Press Ctrl + F to search for touch events.

4.  Make sure Touch events is set to Always on.

5.  Then close out of Edge entirely and re-launch the browser and try using touchscreen / Digital Pen again to validate it works correctly.


For Mozilla Firefox, these are the steps that would need to be done.

1.  Open a new tab in Firefox, and type about:config into the address bar.

2.  Click through the warning.
3.  There will be a search box at the top. Type in "touch"
4.  One of the results will be dom.w3c_touch_events.enabled --Double click that entry. Change the value the browser pops up with to "0" to disable.
For Google Chrome 78 or higher on Windows, you'll need to make a change to the shortcut that launches it.  These steps also work for the Chromium-based Microsoft Edge browser (newest versions of Edge for windows computers.
1. Locate the Google Chrome or Microsoft Edge shortcut on your desktop
2. Right-click in, and select Properties.
3. In the Target box, add --touch-events to the end of the text in there.  An example screenshot is below.
4. Close any Chrome or Edge windows that are currently open, then launch from the shortcut.
