ACAD 2009 - Dim style overide

[PaulMassey]

Apologies if this has already been addressed, I couldn't find a relevant topic.

I am using ACAD '09 (obviously), and every time I open a drawing, it automatically creates a dim style overide. (Basically, the only thing it changes is that it fixes the dim extension lines to 2 units.)

Has anyone come across this problem and a fix?

When did the problem first occur?

Did you recently load a new LISP routine?

BTW, is your version 2009 current with all service packs?

The problem has occurred from the moment ACAD 2009 was installed on my machine. The same thing happened with ACAD 2008 which I was running previously.

No, no new lisp routines, and yes, all current service packs have been installed.

Sounds odd. Two releases and the same problem with both? You wouldn't by any chance be working in a company alongside other AutoCAD users and using a central, networked, repository for many of your CAD standards (like DimStyle) by any chance?
