Made a behemoth of a model, I ensured background geoprocessing was enabled in ArcCatalog, and that the model was also set to be allowed to run in the background. Also, all of the tools that the model calls had their properties set to background processing, and all of the layers were set to be parameters (as stipulated at

Not cool. The model ran in the foreground. Any idea why this would be?

One other thing that is curious is that the option to toggle between running in the foreground or background is greyed out / disabled for all of the ArcToolbox tools (although the 'Always run in the foreground' option is unchecked for all of the tools that I have been using). Not sure whether this is normal or not?
