Its a new feature of IE, the compatibility mode used by a parent page doesn't propogarte to children.
Microsoft ALWAYS break things with every release of IE.

Thank you for your replay, but we already tried this solution and it didnt help us.

I just looked at some system software and got an error code EOO12F11 ... What does that mean?? Well depends on the tool I used, and the context of the error.
This one means that a fan is disconnected from an ECU.
Likewise out of context error codes are not too useful.

I'd look at line 6734 of the base code of the module and see what it is trying to do, what object is involved.
