Hi Chris,

No, still crashes CCL :( 

I know SDL callbacks do work as I managed to filter SDL events which 
requires a callback function. However in this case no data was being 
passed back to the callback function.

I have a feeling that it's the passing of data to the timer callback 
function that is causing the problem.

Typical, 90% of SDL is complete and I'm being driven crazy by a 
single callback.
