Hi,

I'm currently working on my designer for data forms. I load data from
a file and create a fltk::Group and add it to another group. The
problem is that after it's loaded there is not much you can do
anymore. When you close the window the window callback is called and
you can still resize the window and all widgets relayout correctly but
the menu bar and all other widgets don't react on mouse clicks, moves
or keyboard hits anymore.

Any idea or hint what might have cause that? Did anyone experienced
similar behaviour?

I haven't rechecked this problem on Windows and currently experiencing
it under Mac OS X.

Cheers
Tobias
