Hey spacefroid. Sorry for the delay in my response. Been a bit busy lately
I don't see anything unusual in the HJT log. Try this (even though it says it's for XP pro):
Disabling this feature - **Disables part of SP2's attachment manager feature**
To prevent Windows from storing the zone identifier.
for XP Pro:
Click Start, Run and type GPEDIT.MSC
User Configuration | Administrative Templates | Windows Components | Attachment Manager
Double-click "Do not preserve zone information in file attachments"
Set it to "Enabled"
More information about this setting:
This policy setting allows you to manage whether Windows marks file attachments with information about their zone of origin (i.e. restricted, Internet, intranet, local). This requires NTFS in order to function correctly, and will fail without notice on FAT32. By not preserving the zone information Windows cannot make proper risk assessments.
If you enable this policy setting Windows does not mark file attachments with their zone information.
If you disable this policy setting Windows marks file attachments with their zone information.
If you do not configure this policy setting Windows marks file attachments with their zone information.
So, once that stuff is disabled, see if your problem still exists. If it does, please describe to me exactly what you were doing at the time of the problem, as well as any messages you are currently receiving. I know you've stated it before, but I'd like to make sure the problem didn't change any, plus a good mental refresher would be useful as it's been a while since we talked.
