I must admit I am having keyboard fatigue of late. I end up not taking my fingers all the way to the key I want to type and am inadvertantly pressing something else. As a result, I have, from a trillian window, opened up an email in Outlook, or minimized all windows from Word, or modified the heading of a document trying to send an email!
I was so frustrated at my trackpad because I thought it was the trackpad that was causing this nonsensical stuff, but as I tried to study the pattern of such things, I realized it was my lazy fingers! 🙂
