reference - save relative path


I have some dgn files with references who are saved with the relative path. A colleague have to use the files, but his PC uses other dive mapping.

Haw to set all references to "not saving relative path"

I've tried to change the checkbox and save the drawing, but always the save relative path is checked again after reopening the drawing.

Haw can I change this and haw to prevent the use of the "save relative path"

I've set the variables : MS_disallowFullPath=1 but no changes...

Regards Rik
