Thanks Gary and Dennis.
Dennis - same lappy...same OS...
However, I have installed a few small programs since it last worked flawlessly.
The are not running when I use the laptop, but they are there. I've removed a couple since they were just try-and-sees.
I've also installed a few Windows updates in the last few weeks.
I've also got the mouse and ToUcam plugged in on top of each other in the two separate USB ports on the right-hand side of my latop. I've got more USB ports at the rear of the lappy. I'll plug the ToUcam in there and see how I go. However, it's never been a prob before
Plenty of room on the HDD and doesn't need defragging.
Thanks for your help, guys
