Hi David,

Yes, it's rather easy to fix.
I suppose you don't need the title width to set the width of the window, so you can safely set the MinX and MinY values (or at least one of them) to one. This is also the value that the original Acorn Template Editor defaults to.
As far as I know, the problem only shows up on RISC OS 5, but it was introduced much earlier in life. It probably never showed up as earlier systems used a different memory layout. In other words: trying to read the window flags from an out-of-context program might always have lead to an illegal memory pointer being accessed. However, as long as that pointer was pointing to some valid contents, it would work. Apparently, in RISC OS 5 it was suddenly pointing nowhere, resulting in an Abort. 

Best regards,
