I have some questions. First, some background:
On my current project, started by others, the IRD has grown so big that the Report Browser routinely fails if I try to review its contents by loading the IRD. As a work-around, I create a new empty IRD and then, in the Manage Corridors dialog box, I copy each corridor into its own IRD.
However, this makes me wonder - what happens to any point controls using corridor points?
There may be other similar complications, but this is the only one that has occurred to me.
