An update to WeatherCat V3.3.0 test version is now available (build 175, Feb 2024) - please see the WeatherCat Development forum for more details. (Note: Forum registration is required to be able to see/access the WeatherCat Development forum).
Sylvester was replaced with the Twitter client in WeatherCat 3. And yes, there are plans for an RCP based desktop client, but it isn't in the immediate future. A 64 bit client is available as of V3.0.1 - see http://athena.trixology.com/index.php?topic=2755.0 for details.Cheers,Stu.
