XML-Sitemap Generator for WordPress 3.0, page=sitemap.php:
1. Additional pages don't show up. They was saved in the pervious version, and shows in the actual sitemap.xml, but not on this page after saving
2. List of priority options for additional pages show 0 1 0 2 0 3 0 4 ... (no decimals)
3. Priorities settings (at bottom) won't save
Server: Windows Server 2003, IIS, Norwegian localization
Client: Firefox, Norwegian localization
Both using "," (comma) as decimal separator (the problem might be related to this)
I recommend "," not to used as separator in value lists transferred.
