Exception error if database cnx lost

Hi,

If I click on a View/Table... when cnx to database is lost then I get an exception error "Operation not allowed object is closed", should it be handled by a normal dialog box telling you cannot do this because cnx to database has been lost instead of a "rude" MadExcept message ?

version : 9.3.0.4993
compiled with : Delphi XE5
madExcept version : 4.0.8.1
callstack crc : $12861c2c, $75a8f6c8, $7f8ff580
exception number : 1
exception class : EDatabaseError
exception message : SQL Error (0): Cette opération n'est pas autorisée si l'objet est fermé unknown.
