We are having this same problem on several different IBM desktops and laptops also. The DWG Viewer from the Autodesk DWF Composer 2 package loads up the drawing ranging for a few seconds to a few minutes then it shuts down with one of the following errors listed below.
1) "FATAL ERROR: Unhandled Access Violation Writing 0x01c4 Exception at 84e42dh." on the following machine
Desktop 1: WinXP SP2, 512MB RAM, 128MB Graphics Card
2) "INTERNAL ERROR: !laymgr.cpp@987: eLockViolation " on the following machines:
Desktop 2: Win2000 SP4, 512MB RAM, 16MB Graphics Card
Laptop 1: Win2000 SP4, 512MB RAM, 32MB Graphics Card
Can anyone help?
