When you select the Recycle Bin Shredder this operation might take a while to complete depending on your configuration. This is usually caused by an unusually large amount of files in the root of the recycle bin. In order for File Shredder to be able to list the paths of the files to be shredded, a lot of processing power is required. In older systems, this can sometimes cause a delay of several minutes before the application can be used again. If this occurs, please make sure that you empty or shred the content of your recycle bin regularly to avoid this problem in the future.
