When I double-click a Code Inspection result, Excel goes "Not responding" and a few (3 or so) minutes later wakes up. Are 4318 findings a lot in a 30K line project?

This is not practically usable at present.
Of course I could disable many of the default observations but as a first run it's useful to run through them ... if I could only run. I might try exporting to Excel and writing a macro to jump from the finding to the place in the code, without RD running.

is there a General Setting to turn RD off temporarily, as distinct from unloading?
