I've recently noticed that when viewing a set of images in Image Viewer the zoom buttons don't work correctly.
I open an image (2048x1536) on a screen (1280x1024) and set the viewer to FIT, I then click the zoom in button which goes to 75%, 100%, 150%, 200%, 400% but when I click again the viewer displays 800% in the status bar but the image on screen is actually zoomed out to 100%.
With another image (2896x1936) the same happens although at 400% I get a black screen. Clicking again displays 800% in the status bar but the image is actually shown as 100%.
All images are standard jpg's taken with a digital camera.
I'm not sure if this is a new thing or if I had the same problem in previous versions.
I am currently running version 18.104.22.168.3190.x86 (USB). I have a reason for not using the latest version ATM but that's a separate issue which I'll search for an answer first and post back later.
Any help would be most appreciated.
