Shoutbox

1. I thought it did flash the taskbar button?
2. Tab is usually used to move between bits of a window, so this won't be implemented. Use Ctrl(+Shift)+Tab, which are standard tab-changing shortcuts.
3. Do you mean the caption on the taskbar button changes? I don't view that as a problem. Though it's possible to change the caption, it'll also change it for the window (if you have the frame visible).
