It would be great to have a "Limit to Single Instance" or "Reuse Existing Window" option so that multiple sequential calls to ImgBurn (AutoPlay for instance) will focus the current instance of the program rather than launch a new one. Why would this be useful? When I burn DVDs, I tend to make several in a row (I'm guessing this is a common usage scenario) and I would like to have "Build + Burn Image using ImgBurn" configured as the default AutoPlay action for blank DVDs. However, if I do this, after burning the first of a series of DVDs, when I insert another blank DVD, AutoPlay launches a new instance of ImgBurn instead of focusing the current instance. Having this option would allow ImgBurn to respond as expected / required when configured as an AutoPlay action.
