I've got a laptop monitor on the left, and a larger monitor on the right. I'm able to use DisplayFusion (not pro) to use different pictures as the wallpaper for each monitor. I'm using Windows XP, and work in a corporate environment, so my workstation is locked quite a bit (CTRL-ALT-DELETE - Lock Workstation). The dual monitor background image doesn't display correctly when the workstation is locked. The single, composite background image doesn't span both monitors, it is instead applied independently to each monitor. For example, imagine (1) and (2) are the chosen wallpapers. When the workstation isn't locked, the wallpapers are displayed correctly on the two monitors (left is smaller than right). When locked, it gets all messed up.

I get this exact same problem. My left monitor is a 19" 4x3 LCD and my right, main monitor is a 24" widescreen LCD. My wallpapers look great when my machine isn't lock but as soon as I lock it they get distorted exactly as you say.

I wonder if there's a fix.

Can the Display Fusion people not re-create this issue? Is this an unfixable issue?
