Hi once more Dave, I think you are right about VBoxXPCOMM.dll, or its an error thats been carried forward from the early days, clear up to version 4.2.32! I was however mistaken in saying that its needed for os2, its needed for Windoz. VBoxXCOMM.dll is needed for for compiling os2 and got me a bit further in the compile. Thanks again.
