W2K Guest and version 4.2

[DL2DAD]

Hello everybody,

i have a little problem with the new version 4.2 of VirtualBox. Now it is impossible to switch to seamless mode! I have tried it on three different Windows 2000 (two W7 hosts and one Mac) Guests. The switch for seamless mode is grey. Installation of old VirtualBox Guest Additions (Version 4.1.20) helps, but i think that is not the solution! Is there any possibility to install the right Guest Additions AND to use seamless mode?

Thanks for help

Axel
