One is that many of the stations seemed to be mixed up. However, there are two problems with BBC Radio Widget.
You can view the schedule by clicking the little arrow on the right, which reveals a pop out timetable which is handy. Click 'OK' and the widget will spin round and play the station you want. To select a station, click on the 'Info' symbol in the bottom-right hand corner and then select the station you want from the drop-down list.
