You may in a roundabout way have pointed me at where the problem lies. I 
always work with fpc debug libraries as well and I can't catch the 
problem. I changed to the standard release and the bug appears! 
Unfortunately, while duplicating the problem is one thing, tracking it 
down when your main debugging tool is unavailable is another...
