For some reason. When I click the left button on my Studio 1749. My screen blinks or flashes. When I try and drag and drop some thing. It seems to put it in some kind of mode. Pressing the power button seems to return it to the desk top. The other problem is that this seems to do it at any time. when the laptop is loading or in windows 7 64bit.
I looked in the setup (F2) and didn't see any thing related to touch pad or mouse options. So I updated the Bios. to Version A08 from A01. and I still have the same problem. Does any one have any ideas why this laptop is doing this and any ideas on how to get it to stop this.
