I've just posted a pre-release of Sunbird Portable 0.3 for testing. New in this version:
- Sunbird updated to 0.3 Final
- Installer and launcher now Vista compatible
- Added intelligent startup for faster second starts when run from the same location
- Added license agreement to first start
Note: Upgrading data from 0.2 has not been tested (and 0.2 and 0.3 use totally different methods to store calendar data, both local and remote), so please backup your 0.2 profile before upgrading to 0.3. Before upgrading, you should run Sunbird Portable 0.2 from its current location to update the profile and then extract Sunbird Portable 0.3 over it to upgrade.
Please give it a try and post back any results.
