Wireless keyboard and mouse, cursor goes away and text stops typing to window
s there a software to keep the cursor from wandering off or is this a keyboard problem?

When I chat on IRC chat, often ( very often) the text stops typing and the cursor is in another area of screen when I return it with the mouse.

I have good batteries and it just happened to me here too 3 characters did not post and I had to retype them
