Just to repeat (in case you missed it) some versions of Windows (Win9x? NT?) are limited by the Windows API to a maximum INI file size. Off the top of my head I cannot remember if it was 32KB or 64KB.

KiXtart has a documented string limit of 32KB. This is very rarely imposed - however it's possible that it is in this case.

What version of Windows / KiXtart are you using?
