Hi Paul,

I'll log this tick behavior as a bug. For a temporary (but not really convenient) fix, try using CURRENT to overlay a second plot with the same data ranges:

q1 = plot(/test,$
yticklen=1.0, ygridstyle=1, ysubticklen=0.0, $
xticklen=1.0, xgridstyle=1, xsubticklen=0.0)
q2 = plot(/test, /nodata, /current)

Also, whenever you encounter a bug, please send it to Tech Support (support at exelisvis dot com); it's the best way to get this info to us.
