hmo-001 Test Touchpad - right-click not recognized

I was testing Maverick Meerkat on my netbook (Packard Bell Dot M) and it failed testcase hmo-001: double-tapping on the right bottom corner of the touchpad on the desktop does not cause a right-click menu to appear. Instead, the mouse pointer disappears randomly.
