Hi,
I'm using the SWT_AWT bridge to create an AWT frame. On this frame I've
created a JScrollPane and added a custom scrollable Label to this pane. The
problem is that when I push the ALT key down I get the following stacktrace:
java.lang.NullPointerException
at javax.swing.SwingUtilities.getWindowAncestor(SwingUtilities. java:63)
at
com.sun.java.swing.plaf.windows.WindowsRootPaneUI$AltProcess or.postProcessKe

Anyone could help me ?
Best regards,
