so this bug exists for a long time now. And actually, i'm one of the victims of it. So i ran my old tests again - they used to fail with 7.6.00.37. But with Server and SQLDBC 7.6.03.07, they run fine. So my conclusion is, that some work must have been done.
Has this bug already been fixed, although it's still only planned for 7.6.05.01 in PTS?
