Guys,

Sorry I didn't respond sooner, but I have been sick the last few days. I 
have only started looking at the problem again this morning, but have 
already found one interesting thread to follow. Since both of you were 
using custom subclasses of FXTreeItem, I tried replacing the MyTreeItem 
instances in Kevin's example with regular tree items, i.e.

     item = tree.addItemLast(@tree, FXTreeItem.new("... just fine"))
     item = tree.addItemLast(item,  FXTreeItem.new("... choke"))

The program still crashes as before. Next, I tried using the other 
overload of FXTreeList#addItemLast, i.e.

     item = tree.addItemLast(@tree, "... just fine")
     item = tree.addItemLast(item,  "... choke")

and this version does *not* crash. This suggests (at least) a couple of 
possibilities that I need to investigate. Will let you know as soon as I 
have something for you.

Thanks for your patience,

Lyle
