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.
