I've downloaded your Dynamic Web Twain Online Demo project and am testing adding a feature. When viewing more than one image at a time we'd like to double-click on an image and programatically set the view mode to display that one image so that the user can zoom in on it (i.e., set view mode to -1 x -1 so we can zoom).

I've added the following function and registered it and verified that it is firing:

function Dynamsoft_OnMouseDoubleClick(index) {
DWObject.SetSelectedImageIndex(index, index);
DWObject.SetViewMode(-1, -1);

It works as expected in Chrome, but in IE 10 it always selects the first image.

Steps to reproduce:
1. Load the Sample Images - load all three
2. Set Preview Mode to 2x2
3. Double-click on the third image; in Chrome the page displays the third image, while in IE10 it displays the first image.

How can I make this work in IE?

Hi chipdavis,

I have checked your issue in IE 10.

You can try the code below to solve it:

DWObject.RegisterEvent("OnMouseDoubleClick", function (sImageIndex) {
DWObject.SetViewMode(-1, -1);
DWObject.CurrentImageIndexInBuffer = 0;
DWObject.CurrentImageIndexInBuffer = sImageIndex;
Please let me know how it works for you.
