It throws an EAccessViolation Exception. I'll compile IBO with debug
info and see if it yields anything more helpful....and also try with
v4.6 again.

failure is..

This is new code. I manually copied TIB_Connection + TIB_Transaction
visual components from an older project and then create the TIB_Cursor
dynamically from code.
