Using Thunderbird 1.0 (20041206) on Windows XP SP1. Users are local machine 'Power Users'. Every time Thunderbird is started, it prompts the user with "Do you want to use Mozilla Thunderbird as the default mail application?" Clicking 'Yes', 'No' and or selecting 'Do not display this dialog again' seems to have no effect -- upon the next startup of Thunderbird, it again prompts the user with "Do you want to use Mozilla Thunderbird as the default mail application?" Under WinXP's Internet Options control panel, the Programs tab, 'Mozilla Thunderbird' *is* listed as the Internet Program for E-mail. Also of note, running "mailto:" from a Start | Run command line causes Outlook Express to start, rather than Thunderbird. If the user is elevated to Administrator-level access to their machine, setting Thunderbird as the default mail client works and the problem goes away. The inability of a Power User to set their default mail client may be related to bug ID #202497. But even if this is issue depends on 202497, how come selecting 'do not display this dialog again' has no effect?
