Think naruman's fix. Proxy works well. Other problems:
1. The icon of visited URL couldn't diplay in bookmarks menu. It can do in K-Meleon 1.8.0 build19 normly.
2. Some web page has a embedded wmv file. How to install a plugin to view it inside K-Meleon?
Try use K-Meleon 74 Beta 3. Find more modifications. But the proxy setting can't be saved as in Beta 2. This bug is not in K-Meleon 74d. As it is the basic function in internet links or browsers, please fix it soon!
