I'm having a problem with the Play/Pause button on the keyboard. Whenever i pressed it it pauses my music for 0.2 second then plays it back. I don't know what's the problem. Tried searching for driver on Logitech site but it says "This product does not ship with software. It uses the native USB drivers already present in your operating system". Any solutions? I'm using Windows 7 Ultimate x64. Thanks.
But the thing is, I opened my anti-virus avast, then close it. Surprisingly the Play/Pause worked. It worked as long as I don't open anything else, for example a folder.
