Jerry,
In regards to the "natural" keyboard, I realize it's what you get "used to", but I hate that type of keyboard. I learned to type on a flat one and I'll stay with it because I make fewer mistakes.
That said, I'm not sure that there is much you can do about mistakes where you might press a Windows key that brings up a menu, or you press the "wrong" two keys at the same time and the text disappears. The Windows shortcut keys are designed to be that way and if you disable them, you will lose a great deal of advantage.
Still, there are procedures to disable most of the shortcut keys if you really want:
Google Search for "disable Windows shortcut keys"
Disable the Windows Hotkeys (All Windows
Hope this helps.

I have just gotten a Microsoft [un]Natural keyboard. My old fingers don't work so well, so I sometimes, well, often, slightly miss-hit when I am typing. When I do that, strange things happen. I might get all sorts of screens pop up that I have to get rid of before continuing my typing. It might be the Edit menu, or the Filed menu, or the Find screen, a graph, etc. Sometimes, the screen I am typing on will just disappear and I have to start all over again. (I was typing a message in the dratted AOL technical help screen, and it just disappeared when I slightly miss-hit. The same thing has occurred when I have been typing a hotmail letter or a post in some forum.) Very often, even though the cursor remains where it was and is supposed to be, I can't resume typing until I click it. Is this just something I have to put up with or is there any way to eliminate or reduce the problem short of getting a younger set of fingers? Thanks, Jerry
