I have got a bug when I insert an activeX Control into a container

[Cy]

My activeX is made in OpenGL and work correctly. But when I try to insert it in a container on my LabView Interface, I only see a Black Box. But In the diagram, I can have the ActiveX Methods I create. I tried to insert it in a new VI and there was no problem. I don't understand what it doesn't work with my VI Interface (perhaps some properties, I don't know...) and I need some help to solve my problem.
Thank you.

It's obviously something with your particular VI since it works in another VI. Your VI may be corrupt. Try copying the Block Diagram and placing it in another new VI. Then try placing your ActiveX object in and see if it works. Just a thought...
