Re-setting The mask curve not working.

[ggroess]

Mike,
When I use the mask curve in LAB and I select the Mask tab.

Clicking reset does nothing.  Clicking the compare button on the other hand re-sets the mask to the beginning...
to clarify...

If I click the reset button with the mask curve selected.  The curve in the grid... re-sets but the image does not update. 
If I then click compare it resets to the values in the mask grid area.
