First of all, yes, it is built in (has been since 7.0b3). Secondly, since the INIT was essentially a copy of the Memory Manager in RAM form, it dutifully replicates all the bugs in the Memory Manager. Well...not that there are a lot; only a couple. But there is one in 32-bit mode that will corrupt memory. This is fixed in 7.0, but if you use MMInit, it's possible that you'll reintroduce the bug. -- ------------------------------------------------------------------------------ Keith Rollin --- Apple Computer, Inc.

It has bugs that causes some crashes which was a problem while we were testing System 7. If you do have this init, you should remove it and don't pass it around. It does little if anything for you, and the risk is too great. It is NOT an Apple recommend fix for any bugs. Jim Reekes E.O., Macintosh Toolbox Engineering
