V-Ray 3.4 Hypershade goes missing!

[EToth]

Whenever I click render V-Ray hides the Hypershade, which is fine; but wherever it goes, I can't get it back.

My workflow now is I have to click the Hypershade icon, press ALT-F4, and then click the Hypershade button again.

I can't find an option in the render settings to disable this or modify what's happening.

Any suggestions?

That's a bit odd, since we don't really do anything with the hypershade window itself.
What Maya version are you using?

This is in Maya 2017. Maybe it's not V-Ray; but it definitely occurs when I click the teapot or clapboard render buttons. <Poof!> goes the hypershade window off into space.

Can you check if the same thing happens when you switch to another workspace layout? That's one of the new options in 2017 - you can choose different workspaces form a dropdown on the top-right in Maya.

If it still does, and when it happens again, can you run this command in a MEL tab once before you render, but have the hypershade open, and then once after you render and it has gone away.
It will print the coordinates of the hypershade window if it exists and will return nothing if it doesn exist (which means it's either docked or closed). This could give us a hint to what's actually happening.

if (`window -exists hyperShadePanel1Window`)  {
    print `window -q -topLeftCorner hyperShadePanel1Window`;
}
