The HP man makes it look so easy, but he is too fast - - - just touch this, then this, then do that, then touch this to make it full screen, and hey presto - - - -
After over 6 months I still can't use my "magic canvas". All the obvious Windows methods of, for example, making a window full screen won't work, so I have given up and just stick with Windows, a waste of all the software HP have written.
It took me 3 months to turn down the brightness of the screen, which was dazzling. All the help menus ended up with "find the control on the monitor" - - there isn't one! I eventually stumbled on it by accident, but don't know how I did it. BTW lots of other computer users also tried to do it, without success.
I hope the HP man will read this.
