what stick you got F4UDOA, I use a CH fiterstick ( analog and speedkeys software), which has (3) 4 way hats and (1) 8 way hat, I have 20 views mapped,
with using the KP5 modifier.
I too use the back 30/45deg left, back 30/45 deg right, and straight back views, as well as back up 30/45 deg view.
are you trying to look around the head rest on left and right with the KP2 key?
if you haven't gotten it fixed yet, let us know what stick you have and maybe we can help a little better.
