OK Thanks a lot guys. I now know I do not have to search any further.

BTW the limitation is, as far as I tested, not just 9x related. NT/2000/XP OS's might be able to work with large ini files using their own API's but using KIX 3.63 on higher platforms gave the same results... (Which does not explain it 'cause as far as I know kix calls native OS API's doesn't it ?)
It's probably a combination of KIX and large ini files.

Thanks !
