#12 Zoom-In button only zooms original not preview

[r_x]

Version: 1.7.0 on Windows 7 64bit

Program state:

Resize disabled.
An image is selected.
Auto-preview is activated.

When an image is selected and the preview is visible, pressing the "plus" button in the bottom right corner only zooms the original image but not the preview image. This makes a detailed comparison impossible.
