When using the touch screen keyboard, some sort of sticky key function seems to be enabled. Press any key such as “a”, and you get aaaaaaaaaaaa, and it keps going until you get out of keyboard. I am currently using a regular keyboard.
Hi Tim - I’ve never seen that before. Seems like the touch part of your screen is broken, or you have a lot of extra electrons in your finger 
Maybe a bad cable?

Everything else on the touchscreen works properly, just the keyboard when it pops up for data entry .
