Procedure entry point not found in xpcom.dll

[Andr� Weidemann]

Hi,
I installed Mozilla 1.2.1 under Windows XP. It was a new clean installation. I removed all older Mozilla Files from the system before I started including the ones in the Application Data directory.
On first start and and sometimes when using the back button I get the following error message popping up.

Procedure entry point "??1nsProxyObjectCallInfo@@UAE@XZ" was not found in DLL "xpcom.dll"

I had to translate the error message into English since I'm using a German XP.
Can anybody please tell me how to get rid of this error?

Kind regards,
Andr� Weidemann
