We have implemented a drag and drop functionality to manage documents from a GDViewer control. It seems as though there is some kind of default swipe navigation that is competing with our intended functionality. It's like clicking and swiping on the viewer window changes the page, but I can't find any documentation on this as default behavior? Is there indeed such behavior built into the GDViewer control? If so, how would I go about disabling it in favor of our Drag and Drop functionality?
