Temporary freeze on "aquire copy" and "delete"

Whenever I delete an object, my client freezes for about half a second before making that "bunk!" noise. The same thing happens when I Aquire->Take Copy.

Although it doesn't sound like much, this is very troublesome and annoying. Does this happen to anyone/everyone else?

(Hummm, thinking about it, deleting an object places it in your trash folder, so that's probably very similar to aquiring a copy).
