"Action menu" not working in network shared directory (Beta 5.00.2177, Widows 10)

When I select a directory to copy from other computer’s shared folder, “Action menu” does not appear. Neither “Ctrl-O” nor “right arrow” does not work.

When there are multiple completion candidates, “Ctrl-N” and “Ctrl-P” worked.
“ENTER” also worked.

I am using Windows 10 File Explorer. The computer in other side of the network is Windows 7. The directory has about 150 files, having names in English, Korean, Japanes mixed.

Regards

Thanks for the feedback. I’ll test and fix it soon.
