Used the code in: [http://www.kirupa.com/developer/mx2004/thumbnails.htm](http://www.kirupa.com/developer/mx2004/thumbnails.htm) I modified it to allow for thumbnails of varying widths. I did this by adding a global that held the current size of the scrolling movie clip. Original: target\_mc.\_x = hit\_left.\_x+(target\_mc.\_width+5)\*k; Modified: target\_mc.\_x = mcWidthGlobal; mcWidthGlobal += target\_mc.\_width+5; with initial value of global being: hit\_left.\_x This works with a couple of quirks. 1. When I run Test Movie the thumbnails are in reverse order. 2. When I run it from the browser the thumbnails are in a random order that changes each time it’s reloaded. I added a trace in the function thumbnails\_fn(k) to show the value of k. Though k is incremented with a for loop the trace in the function shows the value starting from the highest and then decreasing. When I add a trace on i (k’s value in thumbnails\_fn() ) to the for loop in function loadXML(loaded) it increments correctly. So the trace looks like this for 5 thumbs: 1 2 3 4 5 5 4 3 2 1 I am completely confused about this behavior. Can anyone explain this to me?
