for RISC OS? Yep, it's an Amiga-specific build change affecting the non-RISC OS Sprite loader. There is no impact on RISC OS whatsoever. They do on the Amiga build too, I've just switched over to using the fallback decoder (DataTypes). For those who are interested, DataTypes are an OS plug-in system for various filetypes - the Sprite DataType uses the same base code as NetSurf's non-RISC OS built-in support. Basically I'm saving a few kilobytes by taking it out of the main executable, as it is not something which is commonly used here. Chris
