Thanks for your thoughts. No offense taken. That is not the problem. It seems odd to me that there is no way in the preferences to change axis orientation, as I am sure many people have a preference one way or the other. I have downloaded a fix for this which works well. However, it reverts to the opposite axis upon every restart, and, occasionally, for no apparent reason. I presumed that it had something to do with a recent update, but no one else seems to have noted this issue. I will keep watch for more ideas. Thanks for your time.
