I am using DTPO ver 2.0pb8.
If I select text in my browser and use SHIFT-COMMAND-) to copy to DTPO, the selected text only shows up if I do not add tags.
If I add tags to the dark grey window that acts as interface using this method, the selected text does not show up in DTPO. I hear a buzzer instead.
I have tested this every which way till Sunday: after logging in and out, after a restart with no other apps open other than DTPO and Safari, and since Build pb8 was released.
