security flaw in teamviewer 14

I am a long-time user and lover of your software and have recommended it to many business clients. Just updated to Teamviewer 14 and ran into a blatant security flaw in the free version. I work in IT security for a living and use this software on my personal computers. The ability to blank the remote screen and disable input is essential for security when connecting to a remote computer. I looked at the option to purchase an upgrade just to have these security features but there is no license for personal use and the business pricing is far from reasonable for an individual using it a couple times a month for personal use.
