SQLDeveloper - application without response after using export menu

Question

Hello,
I am using 1.2 newest version with SUN SDK 1.5.09 and XP-Prof (2GB RAM) at 10G.
After executing the sql-script the result data can not be exported. After using the right-click menu for export to CSV, EXCEL ... SQLDeveloper hangs for quit long time without any activity or resonse within the Task-manager of the OS. I have to quit the task of SQLdeveloper.
Running short result queries (~25 lines) the export function works fine.
Is there any parameter to set at startup of the program?
With best regards
Martin

Unfortunately, the running the query again on export bug (which is not dependent on type of export) is not fixed in the current EA1. With tracing on, exporting "select * from <table>" shows the following in the trace file:
select * from <table>
Parse x 1, Execute x 1, Fetch x 156 (7778 rows in chunks of 50)
select * from ( select "COLUMN1","COLUMN2",...,"COLUMNn" from ( select * from <table> ) )
Parse x 1, Execute x 1, Fetch x 1 (50 rows)
My guess (from 1.2 experience) is that this second query which only fetches once is run after selecting one of the export options and before the export dialog is displayed. If this first fetch takes five minutes, then there will be a five minute delay after selecting the export option, before the export dialog appearing.
