iOS UIButton(s) clicking through view.

[IDMah]

Hi all.

Weird one..
I popup an UIView on top of my main window and with a button.
On the iphone it seems to work perfectly but on the iPad any click seem
to get passed down to the mainWindow and ignored by the button.

*I can see it clicking on the layer below.

Yes I tried.

[[self window] addSubview:dumbDumbScreen];
    [[self window] bringSubviewToFront:[[self window] viewWithTag:218]];
   [dumbDumbScreen becomeFirstResponder];// <----- doesn't help !!

Any ideas.
thanks
Ian
