I have been using Paint.NET for a long time, and a few days ago I noticed a slow response when I was using the features (i.e. Affects, Adjustments, Layer Properties). Before, whenever I was making a graphic, the changes I was making would show right at the time of each and every adjustment. Now I notice that it takes several seconds to show any changes I make (i.e. if using GLOW, when adjusting radius, brightness, contrast, all adjustments lag.) Then if I get the desired look I want, it will take several seconds to render. I have not added any plug-ins or changed any settings...the only update that has been done on my laptop is an Adobe update. I am using Windows Vista, by the way. Could you give me a solution as to how to remedy this problem?
Thank you for your time.
