On Ubuntu 10.10, I have recently started to experience this problem:
For some reason Skype won't save any settings except "Sign in on startup". When Skype starts and tries to sign in it is unsuccessful (it shows incorrect password, in red) every time (I have provided the correct password).
I always have to click to show contacts in groups, it does not remember it. Every time I have to go to options and update some notification settings.
I know all these things should be "remembered" by Skype - this problem started only recently. I don't recall fiddling with any permissions that could have likely caused that.
Do you know what the problem might be? I uninstalled (marking for complete configuration removal) and re-installed Skype, but it still remembers my username (why??).
Can I find Skype configuration files on the filesystem somewhere and change permissions for them - or even better - edit the files to set what I want?
