Windows 2000 and Serial Communication

Hello from Denmark

I have downloaded two different Delphi serial communication components for
evaluation but have the following problem:

Everything  is working fine under Win95/Win98/WinNT but not under Win2000.
They do not work under Win2000 Beta.

Is it possible that there is a "bug" in the Win2000 Beta release concerning
serial communication?
is it possible that Microsoft has change something, so serial communication
created with Delphi has to be redesigned?
Do anybody know about this subject?

Any help is highly appreciated.
