On the settings issue, I found a problem with the installer that was causing previous settings to not be saved correctly. I attempted to find a solution that would allow settings from previous versions to be preserved seamlessly, but the solutions were quite complicated and would likely lead to bugs in the future. I decided instead to change the way settings are preserved so that they will be cleanly migrated in future versions. So, as some of you have experienced, you will likely lose your settings on this upgrade, but all future upgrades will preserve your settings correctly.

My apologies for the inconvenience. The problem arose from compatibility issues in InstallShield between the old InstallScript way of doing things and the newer Windows Installer Service. We're now using Windows Installer Service for everything, as InstallScript was overwriting registry settings for previous installations.

Thanks.
