Attachment: Testcase

Test page demonstrating the problem. It doesn't seem to matter if the swf file
exists.

Confirming with Mozilla 1.7a build 2004012808 on WinNT4.

I saw this first on this site: 
http://www.ginger-restaurant.de/lunch.htm

I have NPSWF32.dll Shockwave Flash 7.0 r19 installed.

I have never seen such an error. The last build before I used was build
2004011508. But I have remembered, that I have installed recently the Mozilla
ActiveX control and plugin module for Mozilla 1.6. And I think this is the cause
of the error (incompatible version, because it is official for 1.6).

Reporter, do you have the Mozilla ActiveX control and plugin module installed
(about:plugins or see in the plugins folder for npmozax.dll)? I have version
1.0.0.4 of the dll.

If I deactivate that plugin (rename the dll) and restart Mozilla, the error
disappears.

Yep.. That seems to be it.. Removing mozax.dll from the plugins directory makes
the problem go away..

-> invalid (Plugin Error)

The npmozax.dll file is built for a specific version of Mozilla and expects
certain exported entry points to be there. 

Using the 1.6 version in 1.7a, 1.5 etc. is guaranteed to fail in mysterious ways
or flat out not work at all.
