skype has no more icon in system tray when I close its window. It is still active, as its notifications do appear, but I have no more access to it, cannot make calls, etc. If I close its window and try to call it again, I cannot login because it is already in use. System tray is there but only with sound and printer, and the indicator display does not show it as running.
I've removed the system tray and added it again, and even then skype does not appear. And I've uninstalled and reinstalled skype too.
Any ideas on what to do?
