URGENT: inspiegable gtk+-2.0.6 memory crash

hello, i have a problem: myapp draw a gui reading data from a socket. 
That means there is many widget created at run-time. Under linux 
there is no problem, but with WIN32 i have some crash. The crash 
happen when i put a widget in a fix with gtk_fixed_put(...). I have 
noticed that when crash widget->style and widget->window are NULL and 
the widget is a GtkEntry.
The crash is casualty, after do 3000 to 7000 widget, too frequently 
if there is many GtkEntry.
My app use a thread but all the gui update/create are do in a 
gtk_idle under gdk_threads_/enter/leave().
I dont't known waht to do. Someone have an idea ?
Where i can find doc/src/etc for compiling gtk+2.0 under win32 with 
msvc++ ?
