Graham:It's the long distance .... and it's confusing.
I think I have learned to pick up the mouse off the desk. one swipe to the left moves one monitor width, and pick up track back and another mouse swipe gets me to the end of the second screen. The entire time my wrist has been on the desk. If your mouse was cordless it might be easier.
Maybe I need some mouse/monitor switching software?
Uhh .. maybe. An AutoHotKey script could move the mouse to the other screen if you so desired.
I think the key is that you wouldn't use the laptop's keyboard ... you would just use the screen.
You need a full size keyboard and mouse.
I'm working at half mast today, I think my ESR is higher than Grahams :( Dx: URTI vs. Flu.
