You are getting an Exception D from Ibrowse while it's using the javascript.library. I believe this exception D should not be used on either an '040 or '030 so your memory is probably getting corrupted. Another possibility is that the program jumped into data and tried to execute that data which translated to the Exception D vector. Do you have any other stability problems besides Ibrowse? A bug in Ibrowse is the most likely culprit and this info should be reported to the Ibrowse developers. If you have other stability problems then you should check that your memory and accelerator card are socketed good. You should also check that you have the latest SetPatch. You could try the skip option of SmartCrash and see if it allows you to continue. It probably will crash again with a different reason though.
