Try this and let me know how you get on!
Go to address bar in Chrome and type chrome://flags/#disable-direct-write. There you will see the option to disable DirectWrite. There is a known error with Directwrite on the surface related to chrome. Shut it off and restart the browser (or computer or both). Let me know if this fails to solve the issue!
If you have trouble getting that pesky address bar to let you write with the missing mouse press "Tab" key on keyboard until the address bar lights up in blue.
Excellent! You are very welcome, if you have further questions, feel free to ask, otherwise please don't forget to accept and rate! :)
