diagnostic

[c.o.a.]

Dear all,

Can anyone help me diagnose something that is happening in my mac? when typing a text, the cursor suddenly jumps to a former part of the paragraph and the text gets all messed up. The current sentence ends up written in the middle of a former one!

I noticed that there are certain words that trigger this action, namely "you" and "yours", among others.

Any ideas on what is happening and how to solve this problem?

Thank you
