Thanx for your response. I tried it with twm and both frames appear, so it
seems to be due to kwm (KDE Window Manager).
But still I get messages like this:
Tried to free bogus memory 81c9ea8, ignored
Tried to free bogus memory 81c9f80, ignored
free: double-freed at 8215860
free: double-freed at 82158D8
only with jdk1.1.6 and not with jdk1.1.3. Program was BurnIT-1.0 (ask
www.freashmeat.com for it).
The bug with Swing-Applications and Menu is still there; Menues overwrite the
Menutitle until I move the whole window. This does not happen with 1.1.3, but
happens with both kwm and twm.
Example (you need Swing 1.0.2 for this!):
- ------- cut here --------
import com.sun.java.swing.*;
class SwingBug extends JFrame {
SwingBug() {
JMenu m = new JMenu( "File" );
m.add( new JMenuItem( "Open" ) );
JMenuBar mb = new JMenuBar();
mb.add( m );
getContentPane().add( mb );
setSize( 200, 100 );
show();
}
public static void main( String argv[] ) {
new SwingBug();
}
}
- ------- and here -------
