Do you mean you're updating *to* 0.88 or from 0.88 to 0.89? Not that
it means much in this context but 0.89 is much closer to being
bug-free (though that's in an asymptotic context, of course :-)).

You may want to just use XUnmapWindow() and XMapWindow() rather than
fl_hide_form() and fl_show_form().
Here's a rough little example:
#include "forms.h"
#include "try.h"
void hide_cb( FL_OBJECT *ob, long data )
{
FD_hidden *fd_hidden = ( ( FD_try * ) ob->form->fdui )->vdata;
if ( fl_get_button( ob ) )
XUnmapWindow( fl_get_display(), fd_hidden->hidden->window );
else
XMapWindow( fl_get_display(), fd_hidden->hidden->window );
}
int main( int argc, char *argv[] )
{
FD_try *fd_try;
FD_hidden *fd_hidden;
fl_initialize( &argc, argv, 0, 0, 0 );
fd_try = create_form_try();
fd_hidden = create_form_hidden();
fl_show_form( fd_try->try,
FL_PLACE_CENTERFREE,
FL_FULLBORDER,
"try" );
fd_try->vdata = fd_hidden;
fl_show_form( fd_hidden->hidden,
FL_PLACE_CENTERFREE,
FL_TRANSIENT,
"Foo!" );
while ( 1 )
fl_do_forms();
}
