This is a very confusing UI implementation that I consider to be a bug, since it took me hours to figure out what was actually happening, and led me to believe there were several other bugs present in the software.

In short, when trying to edit a Lip Options element on the timeline, the position of the Scrubber (the green vertical line that controls the current time position on the Timeline) controls which Lip Option element is being edited. This is incredibly confusing.

For example, add two different Visemes to a project, and add Lip Options to both. (See attached A.png).

With the scrubber not overlapping any of the Lip Options element, I am unable to double-click either Lip Option, nor can I right click the Lip Options and choose "Lip Options".

If I place the scrubber within one of the Lip Options, now I can double-click the Lip Options to open it, and I can right-click and see "Lip Options".

HOWEVER, if I place the scrubber within the first Lip Options, and double click the 2nd Lip Options, it opens the editor window for the first Lip Options. And right-clicking the 2nd Lip Options lets me pick "Lip Options", but again it will open the first Lip Options.

The reason this is so confusing is because it makes it seem like the ability to lip options is inconsistent. I can right-click any edit any AccuLips element regardless of where the scrubber is, but the Lip Options cares about scrubber position. For a while, I believed that editing one Lip Options changed Lip Options, because I was double-clicking to open them, which was only actually opening the same Lip Options over and over.

In short, please decouple the Lip Options from the scrubber position.
