Today I was doing some analysis using Spatial Analyst on ArcGIS 10.1. At some moment I wanted to look into the neighborhood settings of the Focal Statistics functionality. I opened the Help of the tool, scrolled down to neighborhood settings and clicked on the link "nbrCircle". This crashed my ArcMap session.
I couldn't believe this happened and thought it was not going to be reproducible, but the second time it happened again. Also using another link, like "nbrRectangle", caused my ArcMap session to crash.
When I open the Help manually (C:\Program Files\ArcGIS\Desktop10.1\help\spatial_analyst_toolbox.chm) and navigate to the Neighborhood toolset and Focal Statistics and click on the nbrCircle link it displays the topic as it should do.
Can anyone reproduce this error or is it just me?
