xpdf zoom-in/out ("-"/"+") doesn't work after "z"/"w"

After I press "z" to fit the page to the window, or "w" to fit the page
width within the window, I'm finding that "-" & "+" is unresponsive.  I can
get it responding again by first pression "0" to zoom to 125%, but I really
hope that this is not necessary.  Is anyone else experiencing this?  I
didn't use xpdf on this computer before, and just loaded the package tonight.
