Jason,
Thanks for the updated files.

I have a small problem with the installation: The compiler reported
that the following methods were not found in base class:
DoMouseWheelDown and DoMouseWheelUp (inIBG_Custin.int/imt)

After I commented (* ... *) the relevant section, the IBOject get
installed. Everything seems OK.

My question is: Am I doing the right thing? Or shall I change the
DoMouseWheelDown and DoMouseWheelUp someother name? Please advice.

Thanks again.

Regard
