File Window>Open with ...

[Darius1968]

So, with IMatch open on my database, I changed - via Windows file types - the default app for AVI files. 
As should be, afterward, this button now opens such files with the desired app.  But, the icon for this button did not update.  (I know it will when I close the database and IMatch, and then, re-open.)  But, I just wondered if this non-automatic-updating is by design?  (No big deal if that's the case.  Just curious.)

Restart IMatch. Problem solved?
