Hi, I just purchased a new Samsung laptop model: NP-QX411-W02UB running WIndows 7. I'm having difficulties with the touchpad. Specifically, I am not seeing any options in the control panel to adjust the sensitivity. The touchpad registers a long click and a short quick as two separate things; as opposed to relying on a double click to open a file, the short click does so while a longer click is necessary if I just want to highlight a file. Any way of changing this? Also, is there any way to disable tap to click functionality? I hope that all is clear. Thanks in advance!
