Not all system errors can be copied (ie the error in Connect to Server telling me that there's no services available at: xxx.xxx.xxx.xxx). Any rhyme or reason to which can and which can't be copied?

Thanks

i'd say it's a programmer's choice, but it should become more common.

a good idea would be for error dialogs to have the necessary brains to create a package, that the user could save, of what the error is about so you could send it to the developers.
