"move" is displayed for mouse movement anywhere in the figure (including over the button).  "down" is displayed when the I click on the button, but not when I click on other areas of the figure.

That is unexpected, at least the "down" part. Does it make a difference if you create some plot in the figure, before adding the uicontrol? (the uicontrol should then appear on top of the plot)

Scrap that. It's not unexpected at all. When a uicontrol has Enable set to "on" (the default), mouse press events do not trigger the windowbuttondownfcn callback. I've to refresh my memory.
