[Insight-developers] ExceptionObject Borland Compile errors

[Luis Ibanez]

Hi Niels,

Have you made any progress on this issue ?

Would you like some help ?

It will be nice to solve it before the Dashboard closes for the day.

I have a Borland build and can help if needed.

Please let me know,



    Thanks



       Luis
