After adding images, and selecting ROI button, the crosshair cursor shows on the image, but clicking or dragging the cursor has no effect. I have no way to create ROIs with this app. I use Matlab R2015b on Windows 8.1.

Hi Slobodan,

Let's try taking this step by step.

1. You start the app.

2. You click the "Add Images" button, select some image files, and they show up in the list on the left. The first image is displayed on the right. Correct?

3. You should not have to click the ROI button. You should be in the ROI-creation mode by default. If you mouse over the image on the right, you should see cross-hairs. And if you right-click and drag, you do not see a rectangle?
