[gtkada] GtkAda, W2K and tasks

[Dominique Canazzi]

Hello.

I am currently writing a GUI for a heavy-computing Ada 95 application,
using GtkAda, with the following scheme:
- the main task performs computing.
- the Gtk main loop is in another task.
- the long-life widgets (toplevel windows, ...) are created
  within the main task, before te main loop task is created.
- some slow drawings are done in other tasks.
- most drawings are done by the main task.
Of course, I protect Gdk/Gtk calls with le Gtk global lock.

All that works fine under Linux (rh 6.2, gnat 3.14a1, GtkAda 1.2.12).

Under W2K (gnat 3.14a1, GtkAda 1.3.12), the program ends correctly
without errors, but some widgets (menubar, statusbar) are never drawn,
and kbd/mouse input is ignored in all my windows. However, all drawings in
these windows are correct (in other words, they seem to react to application-
generated events, but not to input-device-generated events).

Any hint?
