~ Cursor Jumping ~

I am using a MacBook Pro (LION) with a wireless Mighty Mouse. When typing , the cursor jumps back to the middle of another previously typed sentence. How can I correct this problem?

Please forgive me if this has been answered previous.

My guess is that your palm is accidentally touching the trackpad as you type - it happens for quite a few people. Go to System Preferences > Trackpad and make sure "Ignore accidental trackpad input" is checked.

Thanks...will do.

Oh uh...I found this, vansmith. Thought you might like to know.

The "Ignore accidental trackpad input" trackpad option no longer appears in System Preferences. Functionality for "Ignore accidental trackpad input" is enabled automatically, by default for these computers.

It's not there or it's enabled automatically?

Does this happen in all applications or a select few?
