K-5 doing odd things

I have recently updated the firmware to 1.13 and now no beep for focus confirmation, and I cannot find the change in the menus.

Secondly, the LCD display did an odd thing when I reviewed a couple of test shots earlier, The display was like a very poor signal on a B+W television. Switched it off and back on again, and everything is fine, including the shots.
I am a tad worried as on Thursday I am off to Estonia, and don't want to take the K-5 if it is causing issues, or take the K20D as well, adding weight.

Thoughts?

Have faith in the K5. Life is full of surprises you will never know what life will throw at you and when.

I have had version 1.13 running on my K-5 for some time now and have had no issues. Maybe you need to keep an eye on the K-5 and take the K-20 for backup as it may be a hardware rather than a software issue?

Thanks Dave. I hope it was a one-off blip.
It does mean a reconsideration on what I take to Tallinn.
It might be a case of leaving the MZ-5n behind with the rolls of film, and take the K20D instead, purely from a piece of mind point of view
