I have a simple PDF form that has about 8 fields. One of these fields is set to zoom out to "fit page width" on blur. When the view zooms out however, the form appears to be blank. Zoom in or out some more and you see all the information in the fields really is there still. Users are getting confused.

I don't know if this is a screen draw bug or something else. Anyone heard of this? Zoom out = blank looking fields.

The actual actions are:

On Focus
Go to a page in this document
Page 1
Zoom level: Fit Width

On Blur
Execute a menu item
View>Zoom>Fit Page

My Product Information:
Acrobat Pro 9.2, Macintosh

I've seen a few different redrawing bugs in Acrobat, but not this one. Is it just the field contents that do not redraw or does the page content redraw incorrectly as well? Have you tried performing the zoom in a different wa? It's possible that the field event combined with a page operation is the problem. For example, use JavaScript to delay and decouple the zoom from the blur action.

In this case, when the on blur zoom out occurs, the fields appear to be empty, but not the underlying document. Zooming in or out, immediately redraws everything and your information appears to re-appear. I was able to reproduce on Windows and Mac using Reader so I assumed it to be a bug of some sort. For now, I changed the built in zoom "on blur" to a "custom view" and this seems to be working better.

Thank you for the suggestion on what to try. I have found many of your tips to be very helpful. And I have read a bunch of them.
