VCursor.Database crashes

[Beatrix Willius]

The parameters I'm using are the following:  
EVCursorLocation.kServerSide, EVLockType.kNoLocks,  
EVCursorDirection.kRandom

A similar piece of code also crashes:

Thread 8 Crashed:

And here the crashing line must be

dim theTable as VTable = theCursor.Database.Table("Message")
