How to switch on "closed boundary conditions" error message

[intern2011]

Hi. I hatched something and the error message, that it can't determine closed boundary conditions appeared.
Unfortunately it ticked the box "don't show this again".

So now the problem. I would like AutoCAD to show that error message again, but I don't know how to switch it back on.

Thank you very much for you help.

So, I think I can close this thread, because the message appeared again, after closing and reopening the drawing.

For future reference.

If AutoCAD no longer shows error messages such as the one mentioned here the user can get them to reappear by going to Options > System > General Options area and click on the Hidden Messages Settings button. In the next window check off what error message(s) you want to resurrect then click on the OK button.
