Thanks, i'll try that later. Noticed also the errant inputs vanish if any key is pressed. Suspect is the keyboard itself. Assessing the "bother" factor before spending more money on this little thing.This type of error is usually associated with the up/down keys, another thing it could be is a scancode error [search linux scancode errors]
Just got done replacing the platter drive with an SSD though, so I'm $44aud into this affair now. The older of the two boys is chomping at the bit to do something with it. Bad luck him, updates still take their time. He'll get a go soon.
