I decided to look at the driver source now. And I think I found the
bug. If
what I think is right, the bug was introduced in version 10.0.7 (Apr 10
2005) of the driver, and it still exists in current 10.0.11 (Jan 8,
2006).
I will warn the driver developer sometime soon.
So, forget about this. If users start complaining, we can just create a
FAQ
entry for it.
