How can I remove the popup and sound, every time I paste?

How can I disable just the sound? I want the popup.

So this is silly. I have a trial version of clipboard fusion and the constant popup notifications are really stupid. I don't need to be notified that I just copied something. My memory isn't that bad that I don't remember pressing the freaking key. I researched this on your discussion forums and found two entries. First I turned off all of the Show Notifications under tray icon settings then I turned off do not show notifications in advanced settings. I restarted the program. I am still getting the notifications!!! Now what do I do. I really like the program but no way I can buy it with this issue.
