Description

[Shad Larsen]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.0.1) Gecko/20020826
Build Identifier: http://ftp.mozilla.org/pub/mozilla/releases/mozilla1.2.1/mozilla-win32-1.2.1-installer.exe

After installing Mozilla 1.2.1 the browser and quick launch function hangs while
launching.  The Mozilla splash will load and stay on the screen.

I have reproduced this when installing from 1.0.1 and from 1.2.  When
uninstalling and reverting back to 1.0.1 the browser and quick launch work fine.

Reproducible: Always

Steps to Reproduce:
1. Start with 1.0.1 or 1.2
2. Install 1.2.1
3. Attempt to launch Mozilla

Actual Results:  
Splash displays and Mozilla hangs.  When checking the task manager everything
looks normal.  Mozilla is using nominal amounts of memory and processor cycles
are at zero.

Expected Results:  
Browser should launch and load.

Windows XP SP1

Reporter : you *have* to uninstall any previous version of Mozilla before
installing a new one.

http://www.mozilla.org/releases/mozilla1.2.1/

"Installation Notes

Install into a new empty directory. Installing on top of previously installed
builds may cause problems."

Resolving this bug as invalid ?

The first time I installed I just installed over the top.  The second time I did
an uninstall and even removed the profile from the application data folder. 
Whether I performed an over the top install or a clean install after
uninstalling the problem occured.  Forgot to mention that... sorry.

As a matter of usability the solution should not be: You need to install Mozilla
to a clean directory when upgrading to the new version.  The unistall routine
should be written to remove ALL remnants of the previous version and then do the
upgrade to the new version, especially if you are just suggesting they install
to a new directory anyway... save them the trouble.  Even then when possible it
would make sense to allow an upgrade over the exisitng software and such so
settings stay intact.

does deleting registry.dat help?

Under WindowsXP registry.dat does not exist.

> Under WindowsXP registry.dat does not exist.

It may be hidden, set up your win to show all files and folders.
Your problem are probably caused by incompatible themes in your profile, try to
create a new profile or delete chrome.rdf from the old one.
