Was it on Windows where your palettes worked normally? I asked about this on
the forum once and no one said they've experienced this, so it could well be
somethng very specific to my system. I wonder if there is anything in the
palette or drag&drop initialization that would poll drives. There is
non-responding network drive on my system that has turned out to play a role in
similar issues with other programs on my system. Except that usually takes
longer to time out.
Anyhow, for profiling, I guess there is gprof, which is supposed to be pretty
limited, but might still prove interesting? Depending on how much your tweak
helps, it could be worth it to some people to kick in some money to pool
together purchase a license for a commerical profiling tool. I would also be
willing to spend some time trying to instrument the layout code by hand. I've
done this sort of thing before; sometimes it proves effective. I was thinking
maybe add some timers to the start and end of the layout() functions and
accumulate the results, which might tell us which element types are the biggest
issue, and then add further instrumentation there, etc.
