I have just installed 11.10, after erasing the previous version. On 11.04 I used to sync notes of Tomboy with my Ubuntu One account. I am trying to do the same now, but when I set the preferences on Tomboy, it redirects me on a web page for the login. I enter my username and password and all is ok on the web page. So I should just push "Save" button on Tomboy preferences to finish the process, but it is still disabled.
Some ideas about the problem?
