Thunderbird and Firebird standardization (Score 1)

Komatsu Canada Limited plans to deploy Thunderbird and Firebird to our corporate users. After extensive testing, we are pleased with the Mozilla browser's compatibility with our major business partner web sites and it's popup blocking feature. We are very pleased with the mail client's anti-SPAM capabilities. Some of our top current Mozilla issues: 1) The lack of support for Mozilla in the current Sun iCS 5.1.1 Calendar server. Sun advises their new Calendar server, available in the fall, will properly support Mozilla. Presently, from the iCS5.1.1 Search dialog, Mozilla 1.4 fails to add users to a meeting or resources to a group. Sun's suggested workaround: use Netscape 4.7x. 2) Bugzilla bug #47838: The inability to insert Windows screen capture images (ALT-PRINTSCREEN) into a mail message or Composer. 3) Regression Bugzilla bug #205947: MailNews Client does not prompt for proxy authentication upon first load. This currently breaks Thunderbird's ability to display mail with embedded external URLs as it no longer prompts for a proxy challenge. This was working in Mozilla 1.4RC1 but is currently broken. 4) Bugzilla bug #36836: mail conduit for the palm sync
