IE PATCH BREAKING FRONTPAGE PREVIEW:
MS has provided us with this information:
The IE patch (813489) that broke FrontPage preview has done so on purpose
for security reasons and Microsoft now has a workaround for this behavior.
The reason the patch broke FrontPage preview is because IE implemented a
function in their code to prohibit browsing across zones.
There's a registry key that will instruct IE to allow listed applications to
browse across zones. FrontPage is not part of that reg key.
You can enter it manually and get the preview to work again.
Add the DWORD value FrontPG.exe to the following key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\Application
Compatibility.
Set the value to 1.
Please note: Always backup your registry before making any changes, and
only make changes if you are comfortable working in the registry.
