This version will optionally display a GUI for 2 seconds that will allow you to choose which browser to use. If you do not make a selection in the two second window, then the default BrowserMaster behavior will take over. That is to say, it will look at the list of configured browsers, if it finds one that is already open it will use that to open the URL.
To shut off this feature, edit the configuration file found in: C:\Documents And Settings\<username>\Application Data\BrowserMaster and change the ShowGui property to false.
