Hi Bruce. I know what you mean. I am still on v. 1.11, but am sending the camera off for update because of the chance of freezing it up.
You will need to update in increments, at least that is what Sony told me. They said if you are below 1.13 it needs to be done in steps.
The firmware update will reduce the chance of errors from SDHC cards, especially high capacity (32GB).
Good luck.
Bob
