We have captured diagnostic logs which OpenText reviewed but could not glean anything usefull. We have installed AdPlus from Microsoft and are trying that approach right now.
For the most part, the events appear basically random. The only documented trigger is that some people get it when converting a Word document to PDF.
It would seem there are really two symptons. The first is the "Referenced Memory Error" that some people get, other people report that Livelink Explorer will "hang" "freeze" or "lock-up" and their only course of action is to go to Task Manager and kill it. For those who have the hang or the freeze, they are also primarily imacted by converting a Word doc to PDF using Adobe Distiller. It doesn't happen 100% of the time to those who report the issue and it never happens to some people. My guess is that both camps (Referenced Memory Errors and the "freezes") will have the same solution.
