UIPopoverController strange behavior - objective-c

Question

I am using a UIPopoverController and populating it with a MPMediaPickerController to choose songs from iPod library. I have got it working just fine. However, I added a completely unrelated feature ( touch a button and image scale to large size ) and now the UIPopoverController behaves strangely only after using the new feature.
After using the button scale feature, the UIPopoverController appears in a strange manner. It looks like it is animating from a rotated state off the screen and lands in the correct place, but the expected behavior is that it should just appear in the right location.
// code for if the interface is a an iPhone, do not use popup
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone)
[self presentModalViewController:picker animated:YES];
// code if not iPhone uses popover media picker
else {
UIPopoverController* pop =
[[UIPopoverController alloc] initWithContentViewController:picker];
self.currentPop = pop;
// checks if the iPad is portrait or landscape and displays the popover media picker accordingly
if (vertMode == TRUE)
{
// if in portrait mode
[pop presentPopoverFromRect:CGRectMake(668.0f, 846.0f, 10.0f, 10.0f) inView:self.view permittedArrowDirections:UIPopoverArrowDirectionDown animated:NO];
// otherwise if in landscape mode
}
else if (vertMode == FALSE)
{
[pop presentPopoverFromRect:CGRectMake(900.0f, 580.0f, 10.0f, 10.0f) inView:self.view permittedArrowDirections:UIPopoverArrowDirectionDown animated:NO];
}
[pop release];
}
}

OK, well I feel a bit silly answering my own question, but I hope that it may help someone else in the future.
I am not exactly sure why, but in my function for the button that scales the image to a large size, I forgot to add:
[UIView commitAnimations];
the intention of that was to complete the animated movement of the scaling image, I am guessing because I never commit the animation, that it was still in some state of trying to animating things. Then when I called my popup , it made the weird animation occur.
So I fixed this by just adding the above one line!
I feel SO much better figuring this one out! I hope it helps someone else out there.
