Sounds good.

In the meantime, I'm thinking of modifying my program so that it 
won't attempt to display an out-of-bounds number of treeview rows on 
Windows.  Is there there a reasonable way of translating the 16-bit 
limit into a maximum number of rows (assuming the rows are sized 
vertically to accommodate a single line of text in the default 
font)?  Would it be reasonable to allow, say, 20 pixels per row? 
That would make about 1600 rows if I'm doing the math right.
