seems like the most recent UW iteration takes up entire deskop. It won't let other apps take focus. annoying as heck as u can't jot down notes, google, chat, etc.
One way to get around this is have 2 monitors hooked up the computer. open the app on monitor and you have the other free. Worked for me a couple of months ago. Don't know if it will work for you, or if your computer can do that, but just thought I would post and let you know.
I found the lack of multitasking a benefit when doing UW. It actually forced me to stay focused on the questions rather than chatting or checking E-Mail and what not. For taking notes, there is a button in the toolbar which will open a small window for you to jot notes.
