1) My desktop wallpaper would vanish, and revert to a blue screen. I was using Webshots Desktop at the time.
2) Upon switching user, I would get Value Creation Failed messages and eventually get to the old logon page, not the Welcome screen.
I did some research, and found that the Value Creation Failed messages were often tied to themes, etc. I promptly uninstalled Webshots, WindowBlinds, and Logon Studio and went to the standard Bliss wallpaper. I haven't had a Value Creation Failed error since. However, the wallpaper continues to disappear. I think it usually, if not always, happens when my memory is taxed. I have two desktops logged on at a time, each using Firefox. So a pretty good chunk of memory and virtual memory is being used.
I'm pretty sure there is not malware involved. Both Spybot and AVG are updated and consistently giving my PC a clean bill of health. The problems started with reenabling Fast User Switching.
Today, I also noticed some images online not wanting to load. They show up as black boxes only. After a couple refreshes they eventually load, but it still bugs me. Not sure if it's related or not.
So I'm wondering if these might be symptoms of being low on memory as I already know I am. It seems somewhat logical to me that Windows might disable my wallpaper when it gets in a memory crunch (and I found all of one site elsewhere that suggests Server 2003 at least did this), and same with images not fully loading. Is there a good likelihood this is the problem, or any other suggestions? It's not an Active Desktop, nochangingwallpaper registry key, or normal settings issue. Thanks!
