This is from the official Apple TIL ( http://developer.apple.com/technotes/tn/tn1194.html
)describing the update:
" COMPATIBILITY NOTE
CarbonLib 1.0.2, which is not part of Mac OS 9.0.4 but is installed with AppleWorks 6, introduces a change to the way the Event Manager handles Apple event idleProcs. The result is that using Script Editor 1.4.1 with CarbonLib 1.0.2 will result in substantial delays in Apple event processing. Script Editor 1.4.3 and later fixes this problem."
