Thank you for your feedback. It looks like you have uncovered a bug with the RSS Reader. We will investigate and get back to you soon.
Regarding the speed: could it be a slow internet connection? most of the data in Café is pulled from the web.
We've fixed this now. When a user deletes a feed, this is remembered so that it doesn't get overridden by the config file on the server. The config file is the XML that lists what feeds should always appear in the RSS plugin.
The feeds I just unsubscribed returned before I exited Cafe. I unsubscribed again, then exited and upon return, the feeds were restored. I right-click the feed, then select Unsubscribe from the menu.
No, I am not on a slow internet connection. I am able to watch live sports and surf at good speed. Cafe is veeeerry sloooow when the application is first opened. It takes a good 15 or more minutes for response time to improve. It's always been sloooOoowwww. This text I am typing ia a good 5+ seconds ahead of the screen display. The same sloooowww response for scrolling; clicking a button; whatever.
