"Hide Last Item When Running" property

[Dave_Thomson]

This is a pretty trivial question...

I just noticed a property for Text Ring controls: "Hide Last Item When Running". Can anyone explain the standard use case for this? Why is this a useful property? And where is the property for "Hide third from the last item when running"?

It sure isn't obvious what that can be used for. I always read about all changes in LabVIEW, but I must have skipped putting this in my memory because I did not understand when that could be useful. Darren's explanation in that thread should have been in the upgrade notes.

A text ring always have a default value, with this property you can set it to the last, hidden, value and thus force the user to make an active selection.

So you can hide "Make a selection"?

Yes, so "Make a selection" is hidden from the items in the list when you click on the menu.

The thing is, It looks good in Darren's example, but not for me. This is what Darren gets:

If I make a text ring, add some items, set the last as default and run, I get this look:

Before click on Ring:

After click on Ring:

The items menu are above the menu, and also covers it. Looks bad.

These are the values:

In the example there is a System Ring, which actually works well (LV2021).

That "above or below" is annoying. It seems to depend on the location of the control along with the number of items in the text ring. For example, if the control is near the bottom of the screen and the item list would extend below the screen, it appears above the control, otherwise it appears below the control. 

Below are screenshots of the same control, just differing by the number of items.

Forgot to say that I had plenty of room below the control and it still is always above, which is unexpected. I cannot get it to show below like it should.

The System ring works as expected though. (The "Fuse Design" text ring and "silver" does not.)

So we are stuck using a system ring or can that be fixed/circumvented somehow for the others? (I'm sorry I realized I'm hijacking the thread, but its kind of related.)

It seems it defaults to Below, but if it won't fit it'll place it Above. It might be a bug in the Modern one, is it the same in Classic and Silver?
