AWT has not yet been modified to work well with Serialization. When you serialize AWT widgets, also serialized are the Peer objects that map the AWT functions to the local window system. When you deserialize (reconsitute) the AWT widgets, the old Peers are recreated, but they are out of date. Peers are native to the local window system and contain pointers to data structures in the local address space, and therefore cannnot be moved. Workaround: Remove the top level widget from its container (so the widgets are no longer live). The peers are discarded at this point and you will save only the AWT widget state. Later, when you deserialize and read the widgets back in, add the top level widget to the frame to make the AWT widgets appear. You may need to add a show call. Note that JDK 1.1 AWT widgets will be serializable, but they will not interoperate with JDK 1.0.2 widgets.
