'º This is an easy way to get a mouse element into your program. To actually º
'º put in a button i've found that you need to get rid of the fancy cursor.  º
'º                                                                           º
'º Thanks to Claude Gagn‚ for the shell of the mouse program, wherever he    º
'º got it from. If anyone has a use for a Novell Netware look-alike shell.   º
'º (the login screen) they can e-mail me at Eebert@HoTMaiL.com               º
