Tonight we upgraded the Enhanced HTML Editor to version 6 of Ephox's EditLive editor, and this upgrade will fix all Windows Vista compatibility issues that existed before. Several Windows Vista users had reported that the Enhanced HTML Editor would not load -- this problem is now corrected.
Additionally, some Windows Vista users had reported not being able to access the JangoMail web site at all -- this issue was corrected about a month ago. This issue was due to the fact that Windows Vista implements TCP/IP completely differently than past versions of Windows, and the new implementation was incompatible with our core firewall. This has now been corrected.
