TNF popup Menu a No-show

I create a TNF. When I hover over the TNF the four-way adjustment cursor appears and that operates correctly. When I right-click on the TNF, no pop-up menu appears (which I need to individually delete the TNF). Rooted everything (including the 6600) - same problem. I thought perhaps something happened to the right-click translation (cntl-click on the MacBook Pro trackpad), but I am able to use cntl-click in other aspects of the SmartSDR.

I don't want to remove all TNF's since I've set up "permanent" 100hz TNF's to mark all of the band edges.

I keep thinking I'm overlooking something painfully obvious, but I haven't found it yet ...

I have a big pile of abandoned TNFs just below the amateur band - which I would like to recycle... ;-)

Setup: SmartSDR v 3.2.39 on top of Windows 10 on top of Parallels 14 on a MacBook Pro. Flex 6600.

Thanks for your insights,
