Possible bug in 2012.

Could someone check this for me. Its been an issue for as long as I can remember.

If I am working in a part/assembly or drawing and I have the dimension feature manager open and switch windows to another part/assembly or drawing without closing it or ticking the green box, in the window I have switched to the dimension tool doesnt work properly. In the window I have switched to the modify dimension box doesnt appear when I place a dimension or try modifying an existing dimension. If I go back to the first window and close the dimension property manager it then works as expected.

Anyone else seeing this?
