Hello, I am using Windows Home Edition 7. What is happening is that, while writing anything in any application, some characters activate something to do something. It varies. For instance if I open a Browser window and the first letter I type is W then the browser window closes. Often I also get another screen come up that half covers what I'm doing and I have no idea why. There are so many I can only think that somehow I have activated a Shortcuts option and nit has been here a while now. Bit vague, Any ideas?
