Labview 8.5 vi still running in the Background

[dkennedy2010]

I am using an old legacy system that is using Labview 8.5. When I shutdown labview, I get the message "Closing the project will abort some running VIs".  My question is how do I see what VIs are running?  It seems that I have an open reference somewhere, but I am having a really hard time tracking it down. 

Basically, all VIs called are using the run VI node, so it is really hard to follow the code and see what is open at any given time.  Any help would be appreciated.  Thanks

The memory profiler (Tools -> Profile -> Performance and Memory) will list all the VIs in memory, which should give you a starting point to track down which one is still running.
