Keyboard buttons open twice a program

Hello everyone.

I use windows 7 about a month now without any noticeable problem.

Everything worked fine until today when my keyboard (Microsoft Digital Media Keyboard) decided when i click on a button that opens a program (for instance Mail) it opens Thunderbird (which is my preferred mail client) twice. The same goes for the button that open web browser, calculator etc.

I don't use Intellitype Pro and i haven't installed it because i don't need it . On XP i never experienced that problem 3 years now.

Does anyone have an idea ?

This problem occurred today after about 1 month i have Win7 installed.

I have tried restarting Windows.
