How can I allow the cursor to continue moving immediately after clicking the trackpad? I have a Macbook, though I assume this behavior occurs on all of Apple's newer trackpads (the multitouch ones where the entire trackpad acts as a button).

For a split second after clicking the trackpad, the cursor won't move (try it!), even if you continue sliding your finger across it. This probably improves usability in some areas (like double clicking), but I don't like it. Is there a way to disable this behavior?

Edit:

I went to a local Best Buy, and every single Macbook had the same behavior. The pause is for only a split second. If you try spam-clicking as you move your finger across the trackpad, does the cursor move at all? If you click fast enough, it won't move.
I tried moving the curser with my left-hand, and clicking with my right as I dragged. Nothing unexpected happened; The curser changed temporarily during the click then reverted.
