Have you installed IE8? Is your computer fully patched at Windows Update
and is "Cumulative Security Update for Internet Explorer 8 for Vista
(KB972260)" listed in Installed Updates?
What anti-virus application or security suite is installed, is your
subscription current, and is it supported in IE8? What anti-spyware
applications (other than Defender)? What third-party firewall (if any)?
Were any of these applications running in the background when you installed
IE8?
Has a Norton or McAfee application ever been installed on this machine
(e.g., a free-trial version that came preinstalled when you bought it)?
Just asking for now!! Do NOT use such a Restore Point yet!! => Do you have
an available Restore Point which predates the install of IE8?
If you do either of the following, does the behavior persist?...
=> Start | All Programs | right-click on Windows Mail | select Properties
| Start in <=delete the value here (leaving it empty/blank) | OK your way
out & reboot.
=> Right-click on the shortcut you use to start Windows Mail | select
Properties | Start in <=replace the parameter here with
%UserProfile%\AppData\Local\Temp & OK your way out.
NB: Uninstalling IE8 (cf.
http://support.microsoft.com/kb/957700) should
resolve the behavior but you should not have encountered it in the first
place if IE8 was installed properly (cf.
http://groups.google.com/group/micr...er.general/browse_frm/thread/a17d79493eac253d)
and/or if IE8 was fully patched.
