Having problems with soft touch buttons on my Studio 1737

Hi,

My problem is "brand new". It never happened before. The problem is that the button at the left, the one which starts Media Direct, is too much reactive. For example, when I close the screen of the laptop, the button lights and Media Direct starts... I don't have to touch it to make it react! It is the only one taht react like this... So the only way to stop that is to delete Media Direct from my computer. But if I do that, I will no be able to watch Blu-Ray movies.... 

Thanx for your help
