Many thanks Esteban - I will study the code to get a feel for what kinds of approach I would need to use.

It didn���t install properly as you warned - but that���s OK - I only need to peruse the code at this point.

First impressions are that it has a bit of complex detail that handles some of the platform & backend GUI work.

I suppose ideally these would be reworked somewhat so the the Chrono application doesn���t need to deal with any of that stuff?

Nevertheless is is going to be very useful and I thank you for your help :-)

Cheers

Mark
