OK, so there ARE in fact two different versions.

I cannot speak for my customer, but maybe that is the case with him.

However I have a "stock" Mac installation of LC 5.02 on my Mac, which I did NOT alter in any way.
But here the same thing happened, it worked in the IDE, but not in the runtime!?

And on the Mac there is even not revsecurity.dll, I think this functionality is in the engine.

Yo! :-)
