Mac Mail Typing Glitch With Hyphen

Question

Using:
Mac Book Pro (Retina, Mid 2012)
Processor 2.7 GHz Intel Core i7
Memory 16 GB 1600 MHz DDR3
OS X Yosemite, Version 10.10
Mail Version 8.0
Typing words with a hyphen such as "I'll" or "We've" or any hyphen causes the cursor to move in reverse one letter so the text typed separates the letters following the letters following the hyphen.
This is an aggravating glitch with the new version.
Anyone else with this problem and are there any work arounds or repairs?
Thanks for any suggestions, David

Answer 1

Log out under the Apple in the Menu bar.
Log in with Shift key down. (This disables all login items)
If the problem goes away it's a conflict with one of your login items.
Still have issue? Restart in Safe Boot mode.
Safe boot
*  shutdown
*  start the Mac and *wait* for the startup chime to sound
*  after the sound, press and hold down the shift key
*  keep holding and *wait* until the grey  Apple logo appears
*  now release the shift key and just wait (it could take a few minutes)
*  eventually the login screen appears with the words SAFE BOOT
*  continue to login to see if the problem goes away.
Validate your Fonts
How to use Font Book to validate fonts
  1. Open Font Book in your Applications folder.
  2. Select All Fonts.
  3. Now click in the list of fonts and select all (Edit > Select All).
  4. Under File in the Menu bar, select Validate Fonts.
  5. Duplicate fonts will be marked with either the yellow badge or a black dot.
  6. Select to remove or delete duplicates.*
  7. Delete font caches
  8. Restart your computer
* Step 6 – remove or delete duplicates is where the tricky part comes in. You can select to let Font Book disable or remove duplicates, but I’ve found that it removes the one you have not been using rather than selecting the best option. See Font Management in OS X, by Kurt Lang, for more info on fonts.
