After i googled a lot i conclude that This is OS 5 issue. it wont resolve it in OS5. It resolved In OS6. You have to provide a way to move the focus off the BrowserField yourself. I have tried a variety of mechanisms to do this, like detecting Escape in the Screen's keyChar method, the best I have found so far is to use the Menu and give the users the option of swapping focus out of the BrowserField. In general I do not recommend sharing the Screen between a Web Field and any other.
public class LoadingScreen extends MainScreen
{
VerticalFieldManager vertical;
HorizontalFieldManager hor;
String url;
BrowserField browserField;
Banner bannerAd ;
private static boolean flag=false;
public LoadingScreen()
{
//
VerticalFieldManager Veret=new VerticalFieldManager(Manager.NO_VERTICAL_SCROLL|Manager.NO_HORIZONTAL_SCROLL){
protected void sublayout(int maxWidth, int maxHeight) {
super.sublayout(Display.getWidth(),Display.getHeight());
setExtent(Display.getWidth(),Display.getHeight());
}
};
//Veret.setBackground(BackgroundFactory.createSolidBackground(Color.BLACK));
VerticalFieldManager main_mgr=new VerticalFieldManager(Manager.NO_VERTICAL_SCROLL|Manager.NO_HORIZONTAL_SCROLL){
protected void sublayout(int maxWidth, int maxHeight) {
super.sublayout(Display.getWidth(),Display.getHeight()-50);
setExtent(Display.getWidth(),Display.getHeight()-50);

This is a bug in OS5. Its been fixed in os6 and upwards . These are the reasons why you are seeing the strange behaviour. You cannot get the same behaviour in os5. The only thing you could do is a hack, which is to setfocus on the button_mgr . The code will look like this.
// override the invokeAction method
public boolean invokeAction(int action) {
Field f = getFieldWithFocus();
// check the type of field you are looking for ,
//here i am checking if its a verticalfieldmanager
if (f instanceof VerticalFieldManager) {
button_mgr.setFocus();
return true;
}
return super.invokeAction(action);
}
this will setfocus on your button.
