program instability - registry edit

Like many of you, I have been battling instability problems with the different versions of Intelllicad from version 98 on to the latest update. I've installed, uninstalled, reinstalled gone back to previous versions upgraded and still have had problems with program instability. I've disabled autosave, uninstalled VBA and done most of the suggestions that have been posted. I finally tried the windows registry edit that was suggested in program shutdown 2 and could not be happier. I found entries in my registry from versions back to Intellicad 98. I STONGLY RECCOMEND THIS TO ANYONE WHO IS HAVING INSTABILITY PROBLEMS AND HAS NOT TRIED IT. The autocad users tell me that autocad reccomends the same thing before installing autocad. Thank you for the suggestion whoever it was.
