What kind of madness is this?

The bugs I’ve found so far:

1_ Changing an element's properties (renaming a clip, track, or bus; changing the number of channels on buses, etc.) does not update the list; the changes aren't reflected visually, though internally they seem to have taken effect. In other words, the system can still locate the clip, track, or bus using its new name, even though the old name still appears in the list...

2_ Closing or opening the window via the toolbar does not update the list's status.

3_ Closing the window using its close button [x] does update the list's status. However, the toolbar button remains active, as if the window were still open.

Creating new elements, or cutting and pasting an element work, does update the list.
