error message when a re-login is needed

Every so often StarExec requires a relogin. This is OK except for the following: if one ha a page open and tries to do an operation, the only message given is that some Internal Error has occurred. Only after experience does one know to try reloging in if other corrections fail. Please issue a more helpful error message in this case. [Truth be told, most of StarExec's error messages are inscrutable.]
