Hi Graham, thanks for your reply.

I didn't know I could set any memory setting trough Interface Builder!

After your question I looked into and I've seen that it states as Beffered.

I've tried to use the Retained option, thinking that this way I shouldn't use the retain message, but with Retained the windows appears but doesn't accept any interaction.

I'd take a deep look into de Memory Management doc you suggest.

While learning the retain/release paradigm is certainly useful, it is considerably more complex than GC. It is also unnecessary while learning Cocoa. Specifically, GC is intended to be a production quality solution that you can use in your Cocoa applications, without exception. In Leopard, there have been a handful of bugs and they have been addressed through software updates -- not surprising given the rather sweeping and intrusive set of changes needed to support GC. And GC will get better / faster in future releases.

An issue is that the previous releases still exist (retail Mac OS X Leopard boxes are still 10.5?) and that someone may need to support them. And in these cases, I would consider that retain/release is more reliable.

I have a stupid question too. Considering that I sometimes see warnings in Console.app related to Garbage Collection, does this mean that:

- the issue is in the application (Xcode sometimes display warnings for instance) and not in the GC?

or

- that GC is more complex than retain/release in some cases?
