There are three general issues with the intreface:
1) The tooltips of the buttons that are on the bottom of the screens seem to display "below" the visibile monitor area, which makes them unusable
2) The event updates window. I am used to use dual-monito setup and the "Event Updates" window is slightly too big to fit my secondary monitor. Can you please allow for resizing of that window? It shouldn;t bring up any problems, as the layout of this window is rather simple. You can aslo consider the new events to appear at the top of the window, instead of the bottom, which would make the window behave more natural (subjective)
3) If you have scroll bars in the windows - the windows do not allow to focus on them and use the scroll wheel in the mouse
