Sandisk Sansa View Thumbwheel Sticking (not turning freely)

I have a Sansa View.  The thumbwheel frequently sticks (fails to turn freely).  That makes it difficult to manuver through my music library and set the volume.  What can I do to remedy this problem?  Is there a lubricant that will free the thumbwheel up or another technique to free it up?  Please respond quickly.

Thank you in advance,

Wayne

There are a number of discussions from the past here on this subject. They typically revolve around the Fuze or even the older 3200 series, but the techniques should also work on the View.

Thanks for the assist.  I tried the method of blowing on the edges of the thumbwheel.  This seems to have worked, although I may have to use it again whenever the wheel sticks.  Thanks again.
