yes, tapping and software button areas are independent of each other and 
are enabled at the same time. clickfinger and software buttons are 
mutually exclusive (and the former is only enabled on apple touchpads 
anyway). Other than that anytime a click isn't what you expect it to be 
is likely a bug.
