I don't know if this helps, but I just spent several hours fighting something similar.
Finally, I put a blank ContentPanel in the region, stuck a FitLayout in it, and then
stuck my ContentPanel-derived Widget inside it. Now it works. When I put my
ContentPanel directly in the BorderLayout, I could not resize it.

Not able to see why... You didn't post the code you use for adding the center panel...
