With Ext.NET 4.2.0, I'm unable to get a simple menu to activate from touchscreen devices. A simple example is below.
The listener does get invoked, as the custom message shows up in the little display area.
However nothing happens, when viewing the page from Chrome's touchcreen device simulations.
When using the browser from PC, everything works as expected. Please advise, thanks.
