[Solved] rotate in viewport object mode ?

found problems

ob add some verts very far away which could not be seen in viewport normaly
but was able to find these and delete

opened up an old file from 2.49

and I can rotate ob in viewport in edit mode around object

but In object mode darn I cannot rotate around ob

where is the setting for this ?

I see setting for edit mode but not for object mode
or is there another setting for this ?

I tried to open file with no UI but did not change that !

thanks
