Hi Ravi,
Did you want to turn the scanning popup off? You can turn it off in the Agent Configuration (System > Agent > Agent Configuration > "Your Configuration" > Advanced Agent Settings) by setting UI.NO_SCAN.int to 1.
It may not be showing for a few reason, some files are finished processing in extremely quick times depending on a number of reasons. For instance binary files aren't crackable and don't take long to process, but PDFs and excel spreadsheet take a lot longer than most files to crack and process the content.
They also may be excluded by the filter in Agent Configuration. You can pull the Agent logs also and view the events that are processing and the time taken to process it.
Regards,
Dean
