(a) SkypeTest Call successful.
(b) Call to normal telephone number successful.
(c) Calls to a Skype contact results in error message "User Not Found"
(d) Deleted all my contacts and recreated using the Search function. Error remains.
Asked for assistance on the Skype Support Forum about two weeks ago but have had no replies.
Has anyone else experienced this problem? If so, would appreciate help on how to solve it.
As an aside, also had this problem with the short period I used LinuxMint v12 "Lisa".
