I have installed Firefox 10 after de-installing FF 8.
All off a sudden, FF tells me that MOZRTT19.dll can not be found.
However, if I switch ZA to OFF, FF can be started without a glitch. After it (FF10) has started, I can switch ZA back ON and it works without a problem.
What could be the problem and how do I overcome it.

Thanks a million in advance
