[Users] How to preview window opening?

[Thomas Taylor]

Hi fellow clawskers ;)
I prefer to not have a preview pane open when a message is selected.  For some
reason CM (3.8.0) has been opening that pane at the bottom of the message
window when and only when I press "<Shift>+n>".  This is activated in menurc
file.  If I use keyboard direction keys (up,down) to select the preview pane
doesn't open.  This seems to have started within the last two weeks but I can't
determine why.  No updates have been done to either the OS or CM in over a
month.

I've gone through the preferences in configuration and run clawsker but can't
find where this is controlled. The only change to the system was replacing a
video card which shouldn't change program behavior.  

? How can I permanently close the preview pane?

Thanks, Tom
