Text error?

If you are using a cordless keyboard, make sure it is not too close to any other cordless equipment such as a cordless phone on the same desk. I had this problem and that was the reason.

A new keyboard. Even if you clean yours, chances are something has inteferred with the connection between your space bar and the little sensors under the keys. Keyboards are fairly cheap, I paid $13.00 for my latest one and the one I replaced cost me $25 years ago. But it had also gotten to where I looked like I was typing in some foreign language. Invest in a new keyboard and stop stressing over it.

something is stuck in your space bar key of your keyboard making a perpetual connection, pop the key and see if there is spill, or maybe something wedged. Clean it with rubbing alcohol on a q tip. You May have to get a new keyboard.

Try a different keyboard, there may be a problem with your spacebar.
