I am wondering if I hit a bug or a misconfiguration. Under firmware 1.1 switching from single shot to HiRes was as easy as hitting the OK button, selecting the panel 2nd from the bottom, 2nd column and switching to HiRes. After the firmware upgrade to 2.2 I have to go into the menu to activate HiRes, since it is grayed out when attempting the above technique. To get out of HiRes and back to single shot I can use the OK panel technique, but sadly to switch back to HiRes requires the menu button usage. Since I alternate quite frequently this has become an issue. Let me know how your camera works under firmware 2.2. If someone else can switch from single shot to HiRes in the OK panel at least I will then know it is a setting I am missing.
