The Return of IE6 Problems

Hopefully,  this time I have generated more specific and relevant 
information.  I have done regressions to identify the patches that may 
be causing the symptoms.  I have duplicated these results by using 
./tools/wineinstall, make && make depends and wineprefixcreate.  
Although I was not able to get the help engine functional, I duplicated 
the IE6 not running symptom by installing IE6 manually.  Additionally 
these symptoms are current as of a wine compiled from cvs the morning of 
October 30, 2004.

Statement of symptoms:
1.  Until the commit of 20040824 16:00:16 CDT, patch 13475, IE6, when 
installed using Mike Hearn's script ran and the help engine was 
functional.  After the patch, the help engine was not functional.
2. With the commit of 20040927 15:39:42 CDT, patch 13938, IE6, installed 
using the script or manually, would not initialize.

If I substitute system.reg and user.reg from a version of wine compiled 
before patch 13475 for the files of the same names in a version of wine 
compiled from cvs updated on the morning of 20041030, IE6 runs and the 
help engine is functional.

The common denominator for this situation is that these patches modified 
some of the same files.  Patch 13475 implemented itss.dll and modified 
wine/dlls/, wine/ and wine/configure.  A partial 
implementation of advpack.RegInstall, Patch 13938 also modified 
wine/dlls/, wine/ and wine/configure in addition 
to adding /wine/dlls/advpack/reg.c.  Although IE6 would still 
initialize, patch 13937 added advpack to the repository.

I do not have the ability to read the changes and try to interpret 
them.  I can only supply information that I think is relevant or for 
which someone specifically asks me.  I have logs of installing and 
running IE6 before and after the patches.  I have the system.reg and 
user.reg files also.  In addtion I have diff files of the befores and 

This is the difference between system.reg-before-patch-13475 and 
system.reg-after-patch-13938.  This file was "egrepped" for itss|advpack:

This is an excerpt from the difference between user.reg before and 
after.  The whole file is 21k and I will be more than happy to supply it 
if someone wants the whole thing.

> +++ user.reg.after-13938    2004-10-26 20:29:16.000000000 -0500

I didn't use this section from any stance of relevance, but only to 
demonstrate the difference in the number strings in the [Environment] 
lines.  10987xxxxx changed to 10988yyyyy is typical both in the 
system.reg and user.reg files.  This section is typical of numbers of 
lines either present with patch 13938 or absent with it.  There are very 
mand "dword=.............." that are present before patch 13475 and gone 
after 13938.

I have also attached the output of winedbg when running IE6 after patch 
13938 and with the system.reg and user.reg files created from the recent 
version of wine.

I thought that this situation could be the results of the changes in 
wine between now and the time that Mike Hearn wrote his script.  
However, I was able to duplicate the systems by installing IE6 using 
Method 2 from Frank's Corner.

If anyone has any "hacking" they want me to try, I will be more than 
happy to do it.  Also, if someone wants more information, I will be 
happy to send what I already have or generate more.
