Note:  This happened several times, but I just tried to duplicate it (to try to
gather more info), and I couldn't...
Comment 1 Marian Mirilovic 2002-01-29 08:47:10 UTC 
Please add more info, I think that this issue is duplicate of issue
16724, but I am not sure. 

Which version of NB and number of build do you use?

I am closing as duplicate , but this issue should be fixed in 3.3.1
(it's open in 3.3).

If you are running 3.3.1, please reopen and add appropriate
information ?

*** This issue has been marked as a duplicate of 16724 ***
Comment 2 Carl Sopchak 2002-01-29 12:47:08 UTC 
I agree that this is a duplicate of issue 16724.  I'm running nb 3.3,
build 200112102331...

(I tried finding an issue, but obviously missed it :-?)
Comment 3 Marian Mirilovic 2002-01-29 12:51:12 UTC 
That's all right.

Thanks for report.
