Multiple ActiveX Containers

[apatel225]

I'm trying to open 3 Separate PDF files within a LabVIEW front panel.  For some reason, I can only get 2 of the ActiveX containers to show the PDFs.  The 3rd one, 2nd one in the block diagram sequence, just shows a white background and never displays the PDF. 

Does anyone know why this might be? I've attached the block diagram.

What happens if you do NOT close the ActiveX ref?

I think i figured it out:  All i did was add a 500msec delay after closing an ActiveX reference and before opening the next one.  In this case, the extra time isn't too critical for the end use. 

Not sure if there's a better solution to this.
