Spontaneous logout while in Snow Leopard

I am having spontaneous logouts while I am in Snow Leopard. This is happening a couple times a day and it is very annoying. When it logs out it instantly goes to a blue screen and then the login screen appears. When I log back in all my apps have quit and it is like I am logging in for the first time. I did have this happen in Leopard too, but very rarely.

Here are some facts that may help:

MacBookPro5,1
Bluetooth on : apple mouse, keyboard
Network, wired ethernet
Connected to external monitor via mini display port.
All software patches up to date.

Anybody else experience this problem? Any suggestions.

MacBookPro5,1, Mac OS X (10.6), 4 GB memory

I'm getting this too, except that after the brief blue screen, it drops me back on the desktop with all my apps closed, as if I just booted up.

FWIW, so far it's only happened twice, both times while I was switching from one email address to the next in the geriatric AOL program that they discontinued a year or two back.

Hi,

I'm having the same problem. After upgrading to Snow Leopard I am finding that spontaneously I will be instantly logged out of the computer. Upon logging back in, I find the computer as if I had restarted the computer.

My Mac:
MacPro 4,1 2009 Model
2x Quad-Core Xeon @ 2.26 GHz
16GM Ram
All software patches applied
Using OS X 10.6

My initial research is starting to show that the cause most likely is with Microsoft Excel v.X.

Anyone want to help me figure out the problem. I'm an advanced OSX user but probably can't fix the problem alone. But I am willing to answer questions and help diagnose this problem.

*I looked in the Console Logs and found the following notes during the time of the last unexpected logout. I'm starting to think Excel is crashing the WindowServer*

So I've been able to reliably repeat the problem and cause the crash... <sarcasm>yea for me!</sarcasm>

Anyways here are my simple steps to crash the comp

1. Start the computer
2. Open Microsoft Excel v.X (not 2008)
3. Type in a couple numbers into a column of cells
4. Start the chart wizard
5. Try to select the cells that the graph should use
6. Voila! Crash Heaven

I'm having the same issue. Apple BT Keyboard, Microsoft BT Notebook Mouse 5000. The only similarity I can find is that I'm running Entourage 2004. I've had other apps open like Smultron, Mail, iChat, Photoshop, and Safari. I have auto-login, so it was basically logging me out and back in. I originally thought the GPU was changing at random, but the last time it happened, I made sure the GPu hadn't changed.

Sep 8, 2009 1:05 PM in response to Stu Baker

I am having the same exact problem. I am constantly using Excel and I run an external monitor but my Mac started doing this a couple of weeks before Snow Leopard. I had hoped that Snow Leopard would cure it but it hasn't.

I have a theory. _Microsoft released an Office 2004 update Thursday, August 13, 2009_. That is curiously near when I started having problems. Perhaps others who are having problems only since Snow Leopard didn't upgrade and use Excel between that update and Snow Leopard.

If I'm correct, what do we do? Are we all using Excel 2004 or is anyone having this with 2008? I hate to upgrade Microsoft office to make it stable, but I need my machine to work.
