Mac OS 8.5: System Freezes When Opening Help Viewer

I moved my Help Viewer window off the screen, up and to the left, by dragging the window with one of its edges. Now, when I try to open the Help Viewer, my computer freezes.
The solution is to throw away the Apple Help Viewer Preferences. The Apple Help Viewer Preferences are located in the Apple Help Viewer folder in the Preferences folder. Once the old preferences for the Apple Help Viewer are deleted, the Help Viewer then opens at the default position.

Mac OS 8.6 resolves the issue.
