Closed activeX ref, but it's open a while. Closed yet? How 2 tell?

I open and close an activeX reference.  (In case it matters, the activeX commands control a Hamamatsu OEM mini spectrometer.)  Problem:  after the Labview closes the reference,

in reality it is still open a little while.  If I re-run my VI and thereby try to open the activeX connection while it wasn't yet closed, bad things happen.

 

So, how can I check whether the reference/connection is actually closed?  Either this reference specifically, or some way to list all open activeX references, would be cool.

This might be a shutdown issue of your component. If it didn't shutdown yet and you try to reopen it all kinds of evil things may happen. I don't think this is a LV related issue. Here is an ugly idea how to solve it: Do some tests how long a proper shutdown takes and add an appropriately long delay before returning from your VI. IMHO any other approach would involve external code.
