It's very annoying when hitting C-c C-b finally ends up with no errors and closes down the error frame. If I don't create a new small frame, a fresh error will take over one of my other small frames and then close that, too. As a workaround, I add a redundant import just to make sure I always have at least one warning.
Is there an option to prevent it from closing down the error reporting frame when there are no more errors or warnings?
