Debug panel doesn't expand some objects

I have found that sometimes the debug sidebar doesn't expand for some objects:



The highlighted object, $00548c80, is not expandable.

I've also gotten this with regular TList objects. There's nothing particularly special about these objects... not sure what I'm asking for here except that maybe someone who knows the debugger & IDE might look at it and figure out what's going on.

I can see two $00548c80, maybe that has something to do with it. Try openning LastLink ?

Good catch, I hadn't seen that. The second one does open fine. I've just got it with another class that are used as _value objects in this list structure - the last one in the list can be expanded but the first one cannot. This is really frustrating but at least it's a clue / workaround if I can find other occurrences of the objects...
