I have a web application that has now become unresponsive to panning and zooming when trying to use the touchscreen functionality on a device. This has occurred sometime over the last month. Everything was working normally before this occurred. I have tested this on 2 different machines from different manufacturers and it does not work on either one of them,so I believe that it has to be something with the applications itself. The buttons on the web app work fine, it's just when the user tries to pan or zoom with their fingers.
I should also note that one of the machines has a stylus and the pan/zoom functionality works with the stylus. I have looked at the touchscreen settings on each machine and they appear to be set up correctly. I've also looked at the settings within the web app itself, but there isn't much there to configure and there is nothing about any touchscreen functionality.
Has anybody else seen this issue? Any ideas on how to fix it?
