TENGUTECH  Requires work, as does their customer support...

I would have posted most of this on their support forums, but I am still waiting for the confirmation email to join :(

* If you have not entered any domains, and you click the 'scan domains' button the program falls over with the error message:

An exception of class OutOfBoundsException was not handled. This application must shutdown.

* Dates are display in the USA date format, whatever the setting on your computer are.

* The program works out information about the whois for a domain by doing a http request to various sites, then screen scraping. Which doesn't always work. Wouldn't it be better to use the 'whois' terminal command locally?

* Expire dates for domains are sometimes a seeming random date.
