Some people prefer to use a macro to automatically fit the zoom to the window when the application is opened. Another option is what Mark suggests, with a button to do the same thing that the menu can do, though I'd personally suggest just training the users to use the zoom feature from the menu.
I'm not a fan of the zoom feature, though. My issue with it is that things can't scale up consistently. Text that I intentionally emphasized (Arial 14, for instance) may no longer be emphasized, or perhaps everything will appear emphasized. Even worse, text may no longer fit exactly in the space allotted, causing scroll bars to appear, or even simply making things unreadable.
In our shop, we develop for the minimum size in common use - 1024 x 768. If people set their resolution smaller than that, they either need to scroll or View - Fit Zoom To Window. If people set their resolution higher than that, it won't take the full screen, or they can again View - Fit Zoom to Window. But again, I don't encourage people to zoom.
Instead, I sometimes try to put the "zoomable" charts or tables at the lower right, if possible. Then someone can grab the corner of the chart and expand it to fit the available space. My resolution is higher than the common size, so I use this quite often to see additional rows of data, and I feel it is a better use of the increased space than merely making everything larger.
None of that answers your question directly, but I thought I'd widen the discussion a bit, and perhaps give you some things to think about.
