Version 1.14
14 May 2004
Allowed netmask to be a number between 1 and 32 for CIDR. The netmask was
previously limited to a number between 8 and 32.
Thanks to Tyler for the suggestion.

Version 1.13
17 May 2003
Removed checks for valid netmask for given network class.
Thanks to Gray Watson and K.S. Yeap for the suggestion.

Version 1.12
15 March 2003
1. Changed icon and added a colour icon. It is supposed to be two RJ45 
   connectors along with IP and a symbol of a calculator. This is to 
   convey the thought of a IP network calculator :-)
2. Program now accepts a backslash as well as a forward slash as the 
   seperator character.
3. The 'Calculate' button has been centred on the form.
Thanks to Philip Plant for the suggestions.
