Laptop / wife interface issues

Right, I pop down the garage for an hour to fettle bikes, leaving my laptop unattended close to where she is ironing. I come bacj to surf STW, and she’s been watching BBC iplayer – fair enough. However she has managed to switch off the scrolly bit down the side of the touch pad. Any idea how I get it back?

Oh, its come back by itself! Don’t tell her yet cos i’ve just had a moan

Sounds like she moved the page to the right & lost the scoll bar, could be worth trying to get some brownie points tho :o)
