Touch pad on laptop
Hoovering over an item opens it.
What happened to double click.
I have restored defaults in folder options, mouse properties
and ease of accsess center.
External mouse via usb port works perfect?
Driving me crazy
Make sure you have the latest Windows 7 driver installed from the laptop manufacturer. Then use that utility from within the Control Panel to adjust the sensitivity, maybe even consider turning off the tap / click feature.
