Thanks Scott.
thesquire--> you can upgrade if you choose so, I have not spotted any other issues "yet" ;-)
I can confirm that setting the Focus mode selector to Single "S" is working now, however, on Continuous "C" makes the camera and the lens labour hard and would not lock the focus.
This is a bug for fujifilm to fix hopefully, with the next firmware release.
I dont know why they dont allow the firmware to downgrade incase of bugs, if people chooses to downgrade rather that getting stuck with a buggy firmware.
myself coming from a software engineering background, Its not impossible. its just a rule imposed by some software engineer at fuji.
Fuji ---> please, tell your engineer to TDD their code. they know what I m talking about!!!!!!!!. it will keep your fan happier in the long run
