How to close RIR

I realize it may slow down the Revit a bit when you open the RIR. And sometimes it may increase the possibilities of causing Revit crash.
I wonder if it is possible to truely close the RIR without closing Revit?
In my work flow, I may just need to open RIR to finish a small task then I can close it.

No, you cannot truly unload it without restarting. But we would be interested in finding out what is happening.

I see, good to know, thanks Scott.
