原因とソリューション

1. There is a known problem with the Atlassian UI plugin bundled with Confluence 3.0 that causes the loading of several transparent PNG images to fail. See AJS-121. Upgrade Confluence to 3.1 or later.
2. IE 6 performs poorly. Upgrade to Internet Explorer to IE7 or later.
3. Disable HTTPWatch if it's running.
