I have global variable it is a wrapper for a window class, i declared it as global, because window is not modal, and it should stay on the screen until user close it, and when user closes window script calls ShutDown function wich releases contexts and current engine but destructor for that global variable is never called

A variable is simply declared at the beggining of file as
HTMLWindow wndFrame;
....
....
....
void main()
{...
....
}
About type Ok, here now will be several fragments from different files
I made some macros and declared them in ohter file here it is:

//scriptMacro.h

I found my propb with this class, i just forgot to call Begin() at constructor
so nRefCount was undefined.

But i still have alot of leaks, is me registration of the class is wrong ?

tnx.

Clear.
Big tnx.
