Circular links + expandable bug

Say you have arrows linking A->B->C->A where A is the same Box it started with (i.e. total of 3 boxes)
Now make Box A expandable and collapse it.
Result: Box A disappears!

I understand the circular linking causes this but a box should never disappear from the chart permanently. The code should probably check that the originating box which started the expansion doesn't close?

At this time the expand/collapse feature works only with tree-like graphs. You can implement your own expand/collapse logic by setting FlowChart.EventFlags[fOverrideTreeExpanding] and handling BoxExpanded and BoxCollapsed. The built-in collapse function just hides the boxes (box.Visible = false), so you could do the same in your event handlers.
