Thanks @Ferudun for pointing out that all the many screens you have dealt with work with modern browser.
Regardless of whether the browser is out of date - we would like to support as much as possible (within reason). As far as I know these are the options available. It is really just pointer (modern) or touch (older) and then CreateJS has logic to decide which one to use.
The last three circles below use pointer, touch and mspointer events independent of CreateJS and ZIM. We did not get the mspointer events to work on our machine, but it is possible that an older browser might recognize this and not regular pointer events.
We would like to know what it says for their DEFAULT - mouse / touch or pointer or mspointer. Also which drags work if any. And their browser, version, OS and screen.
I tested the example you sent on the interactive whiteboard. Except for MS Pointer, the others work. As I mentioned before, it's necessary to test on older versions of the browsers. I will try installing and testing older versions of Chrome on the interactive whiteboard.
One of the teachers who has reported that some of his interactive boards work and others donât for Topmarks' games, has said that Chrome is set to update automatically and version 143 installed.
His school has Viewsonic boards.
He is yet to test the page but has committed to do so when time allows⌠teachers are obviously busy people!
