iOS bouncy Keyboard - keeps dismissing self.

[IDMah]

Hi Gang.

Happy new years !!!
Well an annoying bug just came up. a real pain to debug.
My keyboard keeps auto dismissing it's self when you are typing.
keyboard is called by a UIAlert. This only happens after many many runs so can't seem to reproduce it.

I think it has something about releasing the UIAlert but again, can't seem to reproduce it on simulator. even after 30 calls.

here's the offending code.

// in HighScoreViewController.h
    UIAlertView *winAlert;
....
// in HighScoreViewController.m
-(void)showWinAlert
{
    NSLog(@"gameTime was:%@",userScore.gameTime);
    
    NSMutableString *messageAlert = [[NSMutableString alloc]initWithFormat:
                                     @"with Time: %@",userScore.gameTime];
    // Testing alert //
    winAlert = [[UIAlertView alloc] initWithTitle:@"New High Score!!!" 
                                                       message:messageAlert
                                                      delegate:self
                                             cancelButtonTitle:@"OK !"
                                             otherButtonTitles:nil];
    
    // if High Score then //
    [winAlert setAlertViewStyle:UIAlertViewStylePlainTextInput];
    [winAlert textFieldAtIndex:0].keyboardAppearance = UIKeyboardAppearanceAlert;
    [winAlert  becomeFirstResponder];    
    [[winAlert textFieldAtIndex:0] setTextAlignment:UITextAlignmentCenter];
    [winAlert textFieldAtIndex:0].text=@"Player Name";
    [myTable reloadData];
    [winAlert show];
}


- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex
{
    NSString *title = [alertView buttonTitleAtIndex:buttonIndex];
	
    if([title isEqualToString:@"OK !"])
    {
        UITextField *username = [alertView textFieldAtIndex:0];
        // UITextField *password = [alertView textFieldAtIndex:1];
        
        userScore.name =(NSMutableString *)username.text;
        //userScore.country =[NSMutableString stringWithFormat: @"Moon base alpha"];
        NSLocale *locale = [NSLocale currentLocale];
        NSString *countryCode = [locale objectForKey: NSLocaleCountryCode];
       
        userScore.country =(NSMutableString *)[locale displayNameForKey: NSLocaleCountryCode
                                                                  value: countryCode];
        
        NSLog(@"Username: %@\n", userScore.name);
        
        [myHighScoreTable replaceObjectAtIndex:2 withObject:userScore];
      
        [myHighScoreTable sortUsingDescriptors:[NSMutableArray arrayWithObject: 
                                    [NSSortDescriptor sortDescriptorWithKey:@"gameTime" 
                                            ascending:YES  
                                            selector:@selector(caseInsensitiveCompare:)]]];
      
       NSLog(@"there are #%i",[myHighScoreTable count]);
        NSLog(@"Name:%@ - Time:%@ = %i",userScore.name,userScore.gameTime,
              userScore.gameTimeSeconds);
        
          
       // [myHighScoreTable removeObjectAtIndex:[myHighScoreTable count]];
        [myHighScoreTable removeLastObject];
        NSInteger indexOfEntery = [myHighScoreTable indexOfObject:userScore];
        NSLog(@"found at: %i",indexOfEntery);
        
        [myTable performSelectorOnMainThread:@selector(reloadData) withObject:nil waitUntilDone:NO]; 
        //[self.view setNeedsDisplay];
        NSIndexPath *indexPath = [NSIndexPath indexPathForRow:indexOfEntery inSection:0];
        //[yourTableView scrollToRowAtIndexPath:indexPath atScrollPosition:UITableViewScrollPositionTop animated:YES];
        
        [myTable scrollToRowAtIndexPath:indexPath
                       atScrollPosition:UITableViewScrollPositionTop animated:YES];
       // self.winAlert = nil;
        
    }
    
}
- (void)viewDidUnload
{   
    NSLog(@"HighScore Unloaded");
    //[NSObject cancelPreviousPerformRequestsWithTarget:self selector:@selector(showWinAlert) object:nil];
   [winAlert resignFirstResponder];
    self.winAlert = nil;
    [winAlert release];
    
    [super viewDidUnload];
    // Release any retained subviews of the main view.
    // e.g. self.myOutlet = nil;
 //[[NSNotificationCenter defaultCenter] postNotificationName:@"hsreleased" object:nil];
}

Any hints on tracking it down would be appreciated.
thanks
