Mixed derivative button on basic input palette

Would you try the mixed derivative button on your basic input palette
and see if it works?  Click on the button and put x and y in the two
subscripts, then put x^3y^4 in the box to the right.  I get 0, both in
versions 4.0 and 4.2. It seems that the Wolfram people could have
fixed this bug by now.

Of course, the kernel is fine, and 
D[x^3y^4, x, y] gives the correct output 12x^2y^3.

I hope I'm not flogging a dead horse.  I did a search but found
nothing on this.

Thanks,

Will
