This is interesting,
My problem is slightly different, I just get sent back to desktop whilst the game is still running! I can click back on to the elite icon on the task bar and get back in and the game continues then in seconds back we go again after which all returns to normal. As I like High res asteroid sites this is very inconvenient since you are normally fighting there and given that I been here since alpha I am at a loss as to why in the last few days, well 1st April or so it seems (weird), this has just started to happen. Yes, does feel like the windows key is being activated but I'm having no issues with the keyboard. That being said I also have a Razer mouse and up to now have never had a problem with that either! Oh, I am not running Norton, ugh!
