I just noticed that the auto rotation of images doesn't work correctly with the latest version of neszt's CHDK port. When taking a picture in portrait mode it is only correctly rotated when the camera is held with the flash on the left side. Otherwise the picture is saved upside down. That's not a very big problem, but it's annoying.
Another issue is that the OSD is not displayed when the display is opened.
It would be nice to have a fix for this, and as well for RAW. (Currently I would have to build my own version with the patch someone posted, but I don't want to do this, so a new pre-built version would be nice).
