TYPING PROBLEM CURSOR GOING BACKWARDS

Since I have installed Yosemite, I have a cursor problem when typing e-mails (only e-mails). When I type an ' like in the word L'IMAGE, my cursor goes back automatically to the letter just after the ' when I am at the end of the word this means instead of typing " l'image parle" it will type "l'iparlemage"

Slightly similar problem with 's in English, the cursor goes back to just after the ' as if not willing to insert a blank. It means I wish to type "Daddy's car" , it types: "Daddy'scar".
This is really boring!
Who could help?

Best regards
