Hi Xecure,
Many thanks. I managed some changes before I received your reply and see they are similar. I don’t much like shooting in the dark however and with your encouragement have now found some more detailed documentation in man synaptics. A good deal of work to read but at least I now have a reasonable description of the parameters and their function. Quite complicated. Part of my problem is that most of the time I use IBM/Lenovo laptops with the red button and disable the touchpad. I keep feeling for the button which doesn’t exist on Dell!
Thanks for your help.
Regards,
Budgie
