And as a user of applications written by those developers, it is a
practice I detest with a passion. Debugging environmental problems is
painful enough without further encouraging applications that lie to
their users as to what has actually gone wrong.

For example, a file not existing, a file being locked by another
process, and the user not having write permissions to the file are
problems that demand very different responses from the user.
Applications that give the same error message for all three problems are
far too common.

Cheers,
Nick.
