I recently noticed, that the number of items inside a group (in my case the global inbox) did not correspond with the number shown next to the group in the navigation pane. After some investigation I found, that DT4 includes the number of versions in its calculation. If I turn off versioning, the number corresponds with the actual number of visual documents inside the group.
While the calculation of DT4 is correct overall, I find it irritating that the number next to the group differs from the number of documents seen in that group.
Is there a way to change that behaviour?
