Okay, now I know what you meant... I selected BOINC itself, and the two tabs put me on "suspend"... I was thinking this was some feature of BOINC Manager that I didn't know about. Sorry, I'm nowhere near Windows-literate, I'm a Mac guy. :-)
I figured that since the paragraph started with "Try the screensaver - in the Display Properties dialog", Screen Saver tab.......
Anyways, what do MACs do for screensavers? Is it part of OSX or is there some external facility that provides it? As far as Windows goes, the "screensaver" is in two parts - BOINC.SCR, which is what the Windows screensaver code talks to, and the science application, which is what displays the graphics (in fullscreen mode). Essentially, BOINC.SCR "presses the Show Graphics" button when Windows starts the screensaver.

Okay, I also can't read. Your point? :-)

It's part of OS X, under System Preferences. There is a "BOINCSaver" (equivalent to boinc.scr) in that list of choices, but otherwise everything works the same. In fact, the screensaver part works very well, probably better than Windows - but the manual "show graphics" part sucks. Doing that opens a "generic" icon in the dock, attached to the graphics display window, that doesn't want to go away, even after you close the window, you _always_ have to use the dock to quit. (Actually, Einstein puts a pic of Albert on the generic icon, so it's a little better...) It's just an annoyance and nothing major, but still...
There aren't that many differences any more between the Mac and Windows, at least not where BOINC is concerned. It's pretty much 95% "cross-platform" compatible.

Thanks.
I've seen changes to the "show graphics" part of the API, but they were made after version 4.82 came out. The dates of the changes are close enough to the release date that I suspect they were made just to fix that problem.
Thanks, Walt. I had no idea that was possible. It worked great.
So, how much does the screensaver slow crunching down, assuming I set it to go blank after 10 or so minutes?

The screensaver should stop running when the screen blanks out.
But until then, it can take 50% of the CPU.
You can see about how much it "eats" by tracking the "CPU time" used by the workunit.
Record the CPU time, wait one minute and record it again. Difference is the CPU time used in that minute.
Do that without a graphics window open, in one minute Einstein should use close to one minute CPU. Select the workunit, click "show graphics" so the graphics window appears and do the one minute CPU time check again. You'll see that Einstein used a lot less than 1 minute CPU, it only got what the graphics thread didn't.
Just to add to what James has posted and avoid someone else having to look it up...
4.43
The semaphore cannot be set again. (0x67) - exit code 103 (0x67)
ERROR! sftIndex = -1711435
None of this rings a bell with me.
Bernd Machenschalk found the source of this bug a couple of days ago. It's one that shouldn't be exercised very often. The fix is incorporated in the new app that we are testing.
