This problem seems to be intermittent with no solid way of fixing the problem. Occasionally, when I use the virtual keyboard, the keys look like they are activating, the letter comes up, however, the screen only records spaces. For example, I try to type the word 'hello' using the keyboard, the letters show up as usual to show what was entered (that larger letter that pops up when a key is selected) but all I get on the actual screen is 5 spaces. It has happened in trying to write an e-mail, text or on social media.
I tried the standard restart as well as a full power down and restart, as well as just closing that particular app window and re-opening, but both solutions are hit or miss. Occasionally it just resets itself and suddenly starts to work properly again.
Ideas?
