This comes straight from our CTO:
"Hi. I think there’s some confusion about what those radio buttons do. You can only select one of the radio buttons. You can’t include some lists, and exclude others, and have just a single symbol.
Maybe an example would help. If you click on a symbol, it will be checked. If you were on “all symbols”, then “only the following lists” will be checked. That means that TI will only display symbols from that one list.
Now if you move the radio button to “exclude the following lists”, the same list will remain checked. If you hit OK now, TI will only show you symbols which are not in that list.
You can quickly switch between these two cases by changing just the radio button. You don’t have to undo one set of lists. You won’t ever get include and exclude at the same time. We set up the dialog box this way so that (like most Windows’ dialog boxes) you can select the controls in any order you want. You can first chose a set of lists, and then say what you want to do with those lists. Or you can choose what you want to do with the lists, and then select the lists. You can even select some lists, then select the right radio button, and then select more lists.
The same is true of the “single symbol” option. You can select that, and then fill in a symbol. Then you can select other radio buttons to look at the other options. As long as the dialog box is open, it will remember which symbol lists you selected, and what you typed in for the single symbol. But as soon as you hit okay, it with throw out the irrelevant settings.
Selecting a radio button is totally different from selecting a tab. Each of the tabs is independent. You can choose alerts and filters and symbol lists totally independently of each other. But on the symbol list tab, you can only choose one of the radio buttons. Whichever one you choose last is that one that matters."
I hope that helps. Thanks
