hi, Peter, I do have an accountID, and I have voted the bug. But it seems the bug you submitted is not quite the same as mine.... Any way, thanks for your help.
PS: Where is the workaround? I see "NO" for workarounds.

If you have a java developer account (it is free, so you should make one) you can vote the bug and maybe it gets fixed... Cheers, Peter P.S. I also posted a kind of fix there. So check it out...
