While it's true that Apple's compositing wastes a great many clock
cycles for minor incremental aesthetic enhancements, and it's
painfully true that the limitations of their APIs requires
developers of tools like Rev and SC to jump through some pretty big
hoops to allow their developers to have default buttons rendered
reliable against even non-Apple-sanctioned-stripes backgrounds, the
actual CPU time Rev takes up to deal with all of Apple's nonsense
was tremendously reduced several versions ago.
Which version are you using? In v2.9 and the last few prior, I
don't recall seeing any idle state exceed 15% of total CPU time
(more than ideal, perhaps, but down several times from what it once
was and may be able to be brought down even lower if Apple changes
their compositing API).
I agree, in times past it was a HUGE CPU hog and now it is down to a
more manageable CPU usage, but still kind of high for my preferences.
Running 2.8.1 on PowerPC G4, a throbbing button takes the CPU from
0.6% to 15.8% (dialog box no background stack window) to 19.5 (stack
visible with a throbbing button on it).
Mail.app goes from 2.5% CPU (foreground no throbbing button) to 12.5%
(dialog with throbbing button).
Really all I want is some way to denote that there is a default choice
and I'd be happy to just have the blue aqua color without the CPU
eating throbbing. Wouldn't it be cool to be able to turn off the
throbbing animation for default buttons but to retain the indication
that it is the default.
Thanks Kee

You are correct. Actually am not using idle, used it as a figure of
speech meaning that the stack / app is just sitting there doing
nothing. My hypercard history is showing. I agree, "idle" as a command
is not the thing to use these days. Thanks for the reminder.
