[Ifeffit] Can't change values in Athena and Artemis on Ubuntu(Feisty)

Hi Carlo Segre, I install Athena and Artemis from your compiled deb package for feisty. When I try to change values in Athena and Artemis, it doesn't work. The only way change the value is click on the plot canvas. I have tried to execute program as root user, but it also doesn't work. Looking forward for you help.
