Can not run multiple firefox windows with version 4

After the upgrade to FF4 the problem started happening. In ver 3 I used the profile manager and was able to run 2 firefox windows at the same time with no problems in Windows 7.

Now when I try to do this with version 4, one firefox window errors out with 'firefox stopped working'

I thought it was due to an incompatible add on or something, so I did a complete program removal, rebooted, cleaned the registry and removed all folders that firefox put on my system. The problem continues.

You can only run multiple version at the same time if the next version is started with the -no-remote switch added to the command line in the desktop shortcut.

"C:\Program Files\Mozilla Firefox XX\firefox.exe" -no-remote -P

I had the -no-remote and -P in my command line.

I ended up reading some more about profiels from the links you provided. I decided to delete the profile and shortcut and start all over. It now works. Thanks
