/*  URLView 2.11
	written by William Kakes of Tall Hill Software.
	
	This class provides an underlined and clickable BStringView
	that will launch the web browser, e-mail program, or FTP client
	when clicked on.  Other features include hover-highlighting,
	right-click	menus, and drag-and-drop support.

	You are free to use URLView in your own programs (both open-source
	and closed-source) free of charge, but a mention in your read me
	file or your program's about box would be appreciated.  See
	http://www.tallhill.com	for current contact information.
	
	URLView is provided as-is, with no warranties of any kind.  If
	you use it, you are on your own.
