I have created a COM object DLL which is called NMB.CSTBIZRULES

An error occurs when the object tries to excecute the command:

nSize = fontmetric(6, This.FontFace, This.FontSize, 'N')

(The value of 'this.fontface' is 'Arial' and the value of 'this.fontsize' is 9.)

The error reads:

OLE IDispatch exception code 462
Error in line 73 Resource manager internal consistency error


Does a COM object 'know' about what fonts in the system? Could this be why this crashed?
