When using Windows 7 and latest Chrome/Firefox, dragging a resource to move it doesn't work. However with IE it does work. Dragging resources works fine in Chrome/Firefox/Safari on Mac/Ubuntu/ChromeOS. Any clues? Most of our teachers are using Windows 7 and Chrome/Firefox as their default browser.
In Firefox on Windows 7 what occurs is that the browser believes that I am dragging the move icon onto the page and it shows the "Add file here" option and then when I let it go, the image loads as the entire browser window.
I tried changing the theme to Formal White and didn't see a difference.
