I just downloaded 2.4.4 on my PPC G5. I run the 1440x900 skin. My screen size is 1680x1050 (22 inch monitor). The large fade image loads as the image for a 4x3 skin. I have to re-apply the skin to get the fade image correct for this 16x9 skin. This has been happening for several versions, since the bug was fixed so that UM loads with the chosen 1440x900 skin.
I emailed a screen capture movie to tech support from an earlier version and this bug has still not been fixed.
