No errors showed in the DBA Studio

[Beatriz Mart�nez Jim�nez]

Hello list,
Oracle 8.1.7. NT4.0
I have created some procedures in the DBA Studio, and when I try to
compile them I get that the procedure status is Invalid, but in the
'show error' window there is no message. The window appears but it�s
completely empty.
Could somebody tell me what happens? Do i Have to configure anything to
display this errors?
A lot of thanks,
