I noticed that when trying to change the on/off setting for contour mode it acted funny in that the cursor keys went fine until I went down to contour mode. Then the left and right did not turn it on or off. Instead it went up one menu selection.
I found that by selecting the menue above and hitting the left or right would eventually change the contour mode from on/off.
It does not change every time you have to hit the cursor keys several times...
Everything else seems to work ok..
