When you probably will encounter this bug ? If you install and run AVIedit at first time or if you run it just after clean installation of MS Windows 9x/NT from scratch. How to reproduce the bug ? Go to Help/About and wait while face draws. You will see an error message and AVIedit terminates. What causes the fault ? At first time run AVIedit tries to use Registry keys that are not created yet. Is there a workaround ? Yes. Run AVIedit and immediately exit. Or, go Options/Preferences and click Ok. This will create necessary Registry keys. Sorry for all the inconvenience. Alexander.
