Model: Acer Aspire E1-731-4699
OS: Windows 7 Ultimate x64
Country: USA

I've installed the appropriate Elantech driver for the touchpad on my laptop (from Acer site), but when I go to the "ELAN" tab in the Mouse Control Panel, the "Options" tab is grayed out and unable to be selected.
I'd really like to be able to set things like sensitivity, turn off "tap" on the pad, etc., because when I type, if the pads of my thumbs come NEAR the touchpad (they don't even have to touch it!), the cursor jumps to wherever the pointer is on the screen. I've seen this sensitivity issue on other laptops, but I am at a loss as to how to address it here with the options disabled.
The only thing I can reasonably see here is to use a USB mouse and disable the touchpad, but I'd like to be able to use my touchpad if I so choose.
Any suggestions?
Thanks!!
