no zoom in korganizer?

[George Avrunin]

I posted this on the general Fedora list a week or so ago and haven't
any response, so I'm asking again here.

On a fully-updated F17 x86_64, I decided to try korganizer again after
not using it for a couple of years.  I would like to zoom vertically in
the calendar section to increase the vertical space per hour (mostly in
the work week view, but also in the day view).  From the documentation
I can find, I should be able to go to Views -> Zoom -> In Vertically,
but all the options in Views -> Zoom are grayed out (in/out x
horizontal/vertical).

I tried with a scratch user account and got the same result, so it's at
least not obviously an issue with my configuration.  Is the zoom
disabled on F17 or do I have a more subtle problem?
