Hope, someone will able to help with my problem.
Since last Skype update the following message "Cannot focus a disabled or invisible window " coming up every 10-15 minutes even if Skype is logged off. Already reinstall a program, but same issue continue. When Skype has been removed from computer - there is no any problems, but as soon as Skype on - this message appears. Even worst - before message shows up computer freeze for minute (completely not responding).
If anyone had the same issue or know/heard anything about that please help me out!
