From the docs;
"WBAllocFast V1.5
================
This tool redirects all Chipmem-Allocs from 136 Bytes (Mousepointer)
or greater to Fastmem. It redirects more allocs than "WBCtrl IMT=FAST".
This way nearly all Chipmem stays free.
Usage:
in Startup-Sequence before "IPrefs"
WBAllocFast >NIL:"
Since the programmer suggests using it this way, who am I to argue? I have been running the program this way, and have had no problems at all.
