Choose object popup bug

The choose object popup appears then quickly disappears

What version and build of Mac Rhino are you running?

Rhinoceros version: 5.5.2 (5F85)

Should i only post bugs that i know how to reproduce?

if this happens to anybody, the way to fix it is to press the down arrow before it disappears.

No, but if I can’t reproduce it, I can’t send it to the developer to be fixed.

That would not be a “fix” but a way to work-around the problem.
I’m still trying to reproduce it.

I am still unable to repeat the problem.

Are you using the trackpad or an external mouse?
Do you have a Spacemouse plugged in?

Please run Rhinoceros > About Rhinoceros > More info
Paste the contents into a plain text file and please send it in a reply.

I suspect there is something special or different about your setup.
This is not a commonly reported issue.

no spacemouse but i am using an external mouse.

If you temporarily disconnect the external mouse does the problem remain?
I tested with and without a USB mouse (just a plain 3-button Logitech), and mine worked fine.
