New 2011 MB Air 4,2 - Spurious trackpad clicks (many)

Question

Hi, I just upgraded from my old Macbook Air 2,1 (late 2008) to a new 2011 Macbook Air 4,2 (13").
This new unit has the glass trackpad which acts as a button when you press it.
I have been getting a great many spurious mouse clicks while swiping over the pad, that cause me to inappropriately select files and buttons, accidentally pick up files and folders and drop them into the folder next to them, yadda yadda.
I tried the obvious thing, which is to go to "Trackpad" in System Preferences, and to uncheck "Tap to click."  All the current system updates as of today are indtalled.  I am still getting spurious mouse clicks when I have fingers on the trackpad, even though the underlying button is never depressed and hence there has been no "clicking" sound.  This occurs with even light touch, and is totally unpredictable.  It happens about once or twice per minute.  It's a royal pain.  Is this a known issue?  Or do I need to bring my mac to a store to have it checked out?
Thanks,
K

Just FYI, I was able to resolve this issue.  I took the Air into the Apple store a couple times, but we weren't able to figure out what was wrong.
Then, while at home, I tried fiddling with the trackpad for the umpteent time (I had tried this before but had not had any luck reproducing the issue).  This time however, I notived that if I pressed down vry carefully with increasing pressure, slowly on the lower edge of the trackpad, I could get the mouseclick to register without actually mechanically "clicking" the trackpad.  E.g. the switch could be activated without the mechanism mechanically registering a click.  I did not notice this was possible the first many times I checked it, because it is actually very hard to do intentionally and requires a *very* steady hand applying gradual increasing pressure.
Apparently, as one is swiping, moving the pointer, and doing various other maneuvers on the trackpad, in this situation, the trackpad registers spurious clicks. If the normal pressure on the pad varies a lot during daily use, you will occasionally get spurious clicks when just the right pressure is there on the pad transiently.
I went into the Apple Store to try this out on the floor models, and found that this was not possible on any of the floor models.  Once I showed this to the Genius representative, he agreed that there must be something wrong with the trackpad.  He said that in addition, there are some screws on the trackpad that can be used to adjust the "spring" or amount of pressure to apply to the pad before it depresses, which he could try to see if it helps, but he felt it was better in this circumstance to just switch out the trackpad, which he did.
Since switching out the trackpad, I have not had a single spurious mouse click so I am very happy with the change.
