hi, James,

I didn't find anything wrong in your code, but I remember having had troubles 
with ansistring initialization some time ago. Maybe you can check if 
'dataDir' contains the correct value when you use it, or simply set the 
filename: 

filename := './data/images/splash.bmp';

Another possible cause might be, if those strings are shortsstrings, that the 
terminating #0 is missing. You could try

filename := './data/images/splash.bmp'#0;

hth,

Anton.
