When running !Photodesk 3.10, if I allow the TwainPDIF module (v0.11) 
to load in the !PhotoDesk.!Run file, Photodesk and the whole Iyonix PC 
using RISC OS 5.16 will crash and lock solid shortly afterwards.
This has only started to happen since the TwainPDIF module was 
32-bitted.  My version of BASIC V is 1.44

As you appear to be using RISC OS 4.02, can't you just use an old 
v0.10 26-bit version of the TwainPDIF module to cure your problems?
