The PowerPC version of this program requires the ObjectSupportLib.
ObjectSupportLib is an integral standard part of current and future MacOS.
If you use System 7.5 or successive version you do NOT need this!
Only if you use version previous of System 7.5 put the ObjectSupportLib in your System Folder.
Do NOT put it in the System folder if you use System version equal or greater of 7.5 because starting from System 7.5 the ObjectSupportLib is an integral part of the System and is already inside!
