Hi, in the previous versions there was the behavior, that when I open an image from a folder with many images, that was larger then the ristretto window it was scaled to fit into the window. When I then clicked on the 1:1 scaling button it was zoomed to 100% of it's original size and I saw scroll bars.
When I then used the arrows of ristretto to get to the next or previous image and this was also larger then the ristretto window ristretto would remember that i had rescaled the image before to 1:1 and would do the same to the image currently displayed.

In the new version (0.0.91) this remembering is gone and i have to hit the 1:1 scaling button for each image which is quite annoying.
