Hi Wellander,
I tried to install the theme in Mozilla 1.7 and the theme was incomaptable. I also tried the theme in Netscape 7.02 (Mozilla 1.0.2), and it worked. It appears that the theme author never updated the theme to work for the newer versions of Mozilla. Maybe you could try to contact the author of the theme to update it so it works with the newest Mozilla versions.
[edit]After I installed the theme, I went to uninstall it, and I can't uninstall this theme in Netscape 7.02. The uninstall theme option in the prefences is greyed out. I have even deleted my old Netscape 7.02 profile and created a new one, and the theme is still there. Is there anyway I can remove this theme?[/edit]
[edit2]I fixed it by uninstalling Netscape 7.02 and deleting the "C:/Program Files/Netscape" folder, then I reinstalled Netscape 7.02 into a new folder. I then created a new profile. The theme is now gone.[/edit2]
