Find Text and Zoom To

Hi,

I received a large DWG file from a collegue with lots of text in.
I 'd like to search for some text and zoom to the found text object.

In the Find And Replace window, I entered in the "Find What" field my search text.
Search In is set to Entire Drawing.
When I click the Find button, the first text object appears in the Context window.
Annotation Type is SimpleNote.

When I click on the Zoom To button, I get an empty grey window.
I'd expect my layout to be zoomed in on this text object.

Is my expectation wrong or am I doing something wrong ?
