I just installed the latest R9Beta updater. Now, when I launch the program, beginning to model, when I press the middle scroll wheel for my custom PopUp, it Pops up, but as soon as I let go of the middle mouse button, the PopUp Menu disappears. See attached video.

I have the same issue on Windows.
Yes, this looks like it got broken in the latest Beta as a result of another requested fix…

Same problem here.
Quick solution before fix:
press and hold middle button and chose command (works with right button too)
or
set up Rhino.Options.Advanced.UseNewToolBarPopUps to “True”

@Chita just to confirm if we are seeing the same:
fast MMB clicking → MMB disappears
slower MMB clicking → MMB stays
even slower (> MMB hold delay) command fires
If you see the same then I think 1 is the current bug you run into

thanks, I reopened the issue
Is this a Mac-only issue?

It actually looks like a Win only at the moment.
