ImageViewer, Annotations & Touchscreen - Annotations don't work well on a touchscreen. Any thoughts?

We're using the Javascript (latest) version of LT in an AngularJS project and want the ability to use annotations on images. This seems pretty straight-forward and works successfully using the mouse.

However, we'd like to use a touchscreen monitor to allow the user to select the type of annotation with their finger and then allow the user to use their finger to manipulate (use) the annotation on the image. This isn't working, again, it does with the mouse, but not with a finger.

We have a dropdown above the image that shows all annotation types and when that is used with a mouse it shows all the different options in a standard HTML select. When used with the finger it shows the options in what appears to be a MOBILE version of the HTML select. Once the annotation is selected with a finger it simply doesn't work. It appears that the finger touch is "grabbing" the image and attempting to drag it (not pan & zoom, but dragging the entire browser page). If I switch to using a mouse, the standard HTML select displays and all the annotations work.

Is there a configuration somewhere that would allow LT to force all objects to still act in Desktop mode when using a finger? It seems odd that it switches based on an action as opposed to a screen size or environment setting.

Thanks in advance,
Chuck
