Microstation crashing when trying to place dimensions

Which particular version of MicroStation V8i SS3 would you be using? The full version number can be located under > Help > About MicroStation.

Is MicroStation crashing when you perform this operation on all files or just this one file? Maybe you could supply an example design file that this has occurred within for testing purposes.

It would also be helpful if you could show the exact workflow being performed along with some screen captures of the tools and settings. Any other information you could supply would be most helpful in trying to replicate your issue.
