Re: removeFromSuperview crash - please help

Many thanks for the reply. This does make sense, but
unfortunately, on trying it, it didn't help - I had
exactly the same crash as I did when just releasing
the views - if I remember correctly something I read
here, I think this might be because
removeFromSuperview takes a couple of cycles to
complete, so I guess autorelease might release the
view before removeFromSuperview completes. Not sure if
that is right, though.

I would really appreciate any other suggestions, as
this has me stumped.

Thanks again,
Keith
