Actually, that's not exactly the problem; the problem is the touchscreen is actually more sensitive, too sensitive in fact. If you move your finger even the tiniest bit during a click, the tablet registers the event as a drag (resulting in a tiny scroll or select) rather than the click you intended. This is compounded if trying to double-click something, though I am uncertain whether double-click problems are solely a result of the newfound sensitivity or also due to a reduction of the "double-click width" (time and/or space) value.

So, in this case, more sensitivity == less sensitive touchscreen because most human finger movements are outside the new, more sensitive tolerances.
