I am not aware of anything that should have affected this.

Will you please update to the latest Beta and test it using that?
Also, I strongly advise that you avoid 4.9.x entirely if you are coming from
4.8.x. This is because I took a wrong turn and forced everything to ANSI
string types as a way to migrate into Delphi 2009 Unicode strings. It wasn't
until IBO 4.9.13.x that I got this all straightened out.

It will be much easier to migrate your code to the latest Beta.
