ABTSOM30.DLL contains a fix for a problem with VisualAge V3.0a on Windows 95 or NT that causes Smalltalk to crash when reloading the SOMsupport feature (or SOMsupport Samples feature) into the image. Sometimes a WIN95 error box for 'IBMST caused an invalid page fault in KERNEL32' is displayed; sometimes not. If running with SOMDDEBUG=3, the SOMDMESSAGELOG contains the message: R6018 - unexpected heap error. Replace the ABTSOM30.DLL file in the VisualAge directory. Product: VisualAge Professional Environment: Windows 95 or NT Version: 3.0a Prerequisites: none
