On the web there's no 1999 areas at all.  Hopefully the lag catches up
soon . . .

Sorry, I was using 1.1.12.  Stupid fingers . . .  the gtk/simple program
works, as do the testdnd and testrgb programs.  The test RGB program
seems much slower than before, could this be related to installing Imlib
1.9?  I do get one warning in the output of testrgb:

I don't know if that is serious/helpful or not.  I was compiling GNOME
when I first noticed this problem, all gnome apps crash right away,
without a window ever appearing.  How do I go about tracking down this
problem?  Is there any chance that some old library is causing this? 
I'll try 1.1.13 as soon as it debuts . .

here's what panel says:
