SYMPTOMS
========

When you use tag replacement within a WebClass template, you may notice that,
after upgrading to Visual Studio 6.0 Service Pack 3, not all of the tag text and
HTML template text gets sent back to the browser. To determine if this problem
is occurring, right-click on the resulting HTML page in your browser and select
View Source. If you do not see an end </HTML> tag, then most likely you
are encountering this problem.

This occurs only under one of the following scenarios:

- You are running the WebClass in the Visual Basic 6.0 IDE.

- You are running the WebClass in production if the template cache is turned
  off (the template cache is turned on by default, so this is not a likely
  scenario).

This behavior does not occur if you have a pre-existing WebClass site and you
upgrade the server to the new runtime. This is because the template cache is
turned on by default. Upgrade to the new run time by installing Visual Studio
Service Pack 3.

RESOLUTION
==========

You need to roll back to the previous version of the WebClass run time on
computers where you use the Visual Basic 6.0 IDE while running your WebClasses.
Follow these steps to do so:

1. Unregister Mswcrun.dll version 6.00.8450 by running the following command in
  the Run dialog box on the Start menu:

  regsvr32.exe /u "<driveletter>:\Program Files\Common Files\Designer\mswcrun.dll"

2. Replace Mswcrun.dll version 6.00.8450 with version 6.00.8169. You can find
  the 6.00.8169 version of the WebClass runtime on Disk 1 in the Os\System
  folder of your Visual Studio 6.0 or Visual Basic 6.0 CDs.

  NOTE: If you get a sharing violation when replacing the WebClass run time,
  stop and start the iisadmin service before attempting to replace the file.

3. Register Mswcrun.dll version 6.00.8169 by running the following command in
  the Run dialog box on the Start menu:

  regsvr32.exe "<driveletter>:\Program Files\Common Files\Designer\mswcrun.dll"

If you aren't running your WebClass application in the Visual Basic 6.0 IDE (on a
production computer), you do not need to rollback to the previous version of the
WebClass run time unless you are planning to turn the template cache off. The
template cache is turned on by default with a default value of 65 (hex) or 101
(decimal).
