Hi there,
I am using oracle "SQL Developer version 1.1.1.25" on my window 2K
machine to access database. Usually when I click that green triangle
to "Execute Statement", I suppose to get the sql output in that Excel
Format Page.

But sometimes, that does not work. When I click that "green triangle",
I don't get anyting at all in that excel format page. It just show me
a blank page.

I am sure there will be some output data from the database, since I
can get the data from that "script output" window for the same SQL
command.

The only way I can do is to restart a new "sql developer" session and
everything becomes normal.

Does anyone know why this happen ?

thanks,

Chun Ji
