You may use XChat for Windows for free for 30 days. If, after this time, you would like to continue using the product, you are required to register. Registration is a one time fee of $19.99 USD (US Dollars) which can be paid using the PayPal service below.


Q. Why can't XChat for Windows be free?
A. It's free to try for the first 30 days! Building XChat for Windows is a difficult process, it requires quite some skill and expertise to accomplish. It takes time, and is by no means automated. This version also has some value added features only for Windows, such as opening irc:// URLs from your web browser in an existing instance of xchat, spell checking and graphical emoticons.

Xchat usando muita memória?

Lendo a FAQ do X-Chat no link, acabei encontrando uma resposta para o grande gasto de memória que causa o programa.

1. Why does X-Chat leak so much memory?

The simple answer is, it doesn't! There are some GTK+ pixmap based themes around that leak a lot of memory. Please try using a different theme and see if that resolves the problem. X-Chat itself only allocates about 40kb of memory through malloc()!

Ou seja, os próprios desenvolvedores do programa não tem uma explicação exata para o exagerado gasto de memória do programa, por meio disso acabei fazendo o que eles recomendaram, troquei o tema do programa e os 40mb de memória que o programa estava usando com o tema default, passou para 6mb.
