I have been using GWTDesigner for a while and I have been working around an irritating problem. The problem has to do with the designer page size. It seems to be more or less random when I open a widget in the designer. I can temporarily resolve the problem by opening the preview window and resizing it to the size that I desire. After closing the preview window, the design page size changes to match that of the preview window. Everything is okay until I have to open the widget design window again.
I am running the latest version of GWT Designer with GWT 1.7.1 within Eclipse 3.5 on Mac OS X 10.6.1. Though this problem has be consistent for quite a while in various configurations (all OS X).
Ciao,
