Microsoft Edge Two-Finger-Tap Context Menu on Touch Displays

[LegacyPulsar]

IT Manager at a special needs school here, so we use a lot of cause-and-effect touch programs. We just invested in some lovely ViewSonic 65" displays which classes have been using well, but one teacher has noticed that when a certain student interacts with the screen, the context menu keeps appearing in Microsoft Edge which then disrupts the activity. It turns out this is because the student is touching the screen with two fingers, which Edge - JUST Edge - is apparently treating as the command to open the right-click context menu. As we're a special needs school, simply telling the student to only use a single finger or a pen isn't necessarily an option, as depending on the student interaction could be anything from one finger to a whole palm (or elbow, or face).

 

I tested on a BenQ screen that we also have and found that the issue is also there, so it's not an OS or screen-specific issue - it literally ​only​ occurs in Microsoft Edge.

 

The setting is not enabled in the Windows 10 OS under Devices > TouchPad (this setting doesn't even appear) so it's not the two-finger-tap option that can be found in there.

 

Now before anyone says "use a different browser, Edge is rubbish lulz" we use Edge over Chrome etc. due to the very good built-in learning tools and the invaluable Immersive Reader. and would like to continue using it.

 

I've been all through Edge GPO and the regular Settings/Experimental Features menus but can't find anything that looks like it could control this.

 

Has anyone else come across this and found a way to disable it? We're currently on v.105.
