Dimensioning problems in Layout

Having trouble with dimensions in layouts. every time I dimension a radius on an object edge, the layout detail reverts to top view, zoomed to extents, and I lose scale and location.

Rhino gives me trouble resetting the layout detail to the view I want. Usually have to attempt it 2-3 times before it will set to the view I want. I’ve opened the layout detail and tried the toolbar to change the view, I’ve tried changing the view from the layout drop-down menu, same results.

Thanks for the report. Can you run the command SystemInfo and copy/paste the results back here please? Also, can you post a simple file with a layout and instructions to reproduce the problem after DimRadius? Thx
