Yeah. I saw that. I haven't checked the VCL source but I suspect even
calling BeginUpdate will likely still involve the Items TStrings wrapper
trying to talk to the dead COMBO to ask it to not repaint as items
messages are sent. Catch 22.

The destructor is obviously too late to talk to Items on a Tcombo (at
least, unless you hold your mouth right). That's the problem with leaky
abstractions (i.e. wrappers) and mismatched lifetimes. The VCL can only
hide so much behind it's skirt whilst still tring to leverage the
Windows builtins. 

Don't get me wrong. Borland did a pretty amazing job, but I sometimes
wonder why they spent so much time cleverly wrapping the nasty windows
builtins and replicating the faulty dialog manager design.

I suppose it all looked like a good idea when they started. i.e. first
90% done, only remaining 90% left to go.

But using TCombo replacements written in pure Delphi would have been so
much simpler as a design model.  It sure would have obviated the
Kylix/CLX deadend for Borland, but anyway, that boat has already sailed.

Or you can go and build your own boat :-) Did Bristol ever get into
shipbuilding? <Insert analogy here>

TTFN,
