I observed the same behaviour on different xp machines. PCs are completely locked and have to be powered down.

I've been running S@H for a couple years now, since upgrading from the old classic version, with no problems. All of a sudden in the last couple days my PC would lock up a few moments after the screen saver stated. This coincided with what appeared to be the software updating itself (?) to version 5.27. I'm running a pretty clean installation of Win98SE, and have eliminated all other causes. I've had to disable it until I can figure out a solution. Any help would be appreciated.

Try to see if using the blank screen saver helps. BOINC will run as a background task anyway.

To all; sounds suspicious to me....

Look here.

I can't really help you more on the screensaver other than suggesting you look at the Display Property - Boinc Screensaver - Setting. (I don't remember the specifics for Win98)
I use the power setting to blank the monitor.

Personally when I want to know what Boinc is doing I open the Manager to the Work tab and check the CPU time column. It update every 5 sec.

As to the double post just go to edit of the duplicate post.
Select all, delete the text and click on ok.
It doesn't completely remove the post but cleans up the thread a bit.

I ran Boinc on Win98 for a year and and it ran well, but there are a few minor issues you may wish to be aware of.

1. Win98 does not like the new screensaver. I woudn't activate it. It used to crash my system. Besides it just wastes cycle that can be better used to crunch WU.

2. You can set Boinc to run always. I found that it didn't interfere with the normal use of my computer. The only exception where program that made heavy use of graphic, such as movie renderings or some of the newer heavily graphic using games. I just turn off the crunching while playing.

3. If you decide to do more than 1 project, do not use the option 'leave in memory'. Win98 has strange hiccups that causes it to not switch properly from one application to another, causing it to try to crunch more than 1 application at a time and very little work is actually done.

4. Boinc doesn't always shut down properly when you try to exit Win98.
This file should clear up the shut down problem.
Download and unzip into your windows directory the file Default.zip to instruct Windows to close the SETI CLI when exiting. You may need to reboot after to activate this change. Note this windows patch doesn't always work with Windows 98 original edition. The file you are unzipping is called _Default.PIF and contains the information to tell Windows to honor application close instructions. It only impacts 16 bit (DOS) and 32 bit console applications.
