With the current update the "Float this panel" option seems to be broken. I have tried to float several resources; e.g. ESV Bible. As soon as the panel floats the menu bar on the main screen is unresponsive and I cannot get Windows 'focus' on the main screen. It is interesting that a lot of the pop-up functions still work including the "Information" window. However I cannot highlight text in any resource, lay a cursor down in any text box, start a search, or change a tab.
This makes multiple monitor configurations pretty useless.
System: Dell Latitude laptop with XP SP3.
