I have set my Preview button to work in tandem with the Main Dial to switch from DX to 1.3X Crop mode. If I set the camera to 1.3x crop and then use the multi-selector to choose a focus point the camera switches back to DX. The same thing happens once I half depress the shutter release button, press the OK button, press the AF-L/AE-L button (which is set for AF), or press the Focus Mode button. Simply put, the camera will not stay in crop mode if I use the Preview / Main Dial to set it.
However, if I put the camera into 1.3X crop via the I-button, this does not happen...it stays in crop regardless of other buttons being used.
Does anyone else have this problem? (I don't believe that this occurred prior to the 1.009 firmware update - a glitch perhaps?)
