Clarify IVI And 3D Fail To Start Due To Corrupt File

IVI And 3D Fail To Start See long Description for details. LX system running 9.1 software. When the Customer clicks either IVI or 3D in the browser to start up the application, nothing happens. No errors are seen in the apps screen. If you look in /usr/g/service/log you will see a core.mvox file created on each attempt to start IVI. The FE tried reloading IVI and 3D option MOD's but no change. This had been working the day before. Took a look at the /export/home/sdc/Prefs Voxtool.prefs file and the VoxtoolPrefs directory. Ownership and permissions are as expected. The contents don't look like anything strange. As a test, renamed both and then tried to start IVI just in case there was some corruption that couldn't be seen. This didn't help. Tried this experiment of renaming this file and directory on a target at MR and found that IVI will start without these and will actually create a default for both. The FE had just done a saveINFO about a week ago and IVI was working at that time.
