Other issue ... Controls inside Grid (with GridLength/Star) are not resized when browser window resizes. The same XAML in my WPF application works fine.
Any date to fix these issues ("GridSplitter moving" and "Control resizing after browser resizing") ? I would like this fix (or temporary workaround) to continue the development of my project. If necessary I can send by email my key (C#/XAML for HTML5 Professional Edition).
