Re: A slight flicker...any general rules

>From my own experience I believe the flicker is related to the operating
system.  I use GTK 1.2 and have an app that runs under SCO Unix 5.0.5 and
under Solaris 8.  I also change the colors of buttons and there is quite a
bit of flicker under SCO but none under Solaris.
