Why do many of my apps not show the version number?
I'll get an email that this or that program of mine needs updating. However, when I go to see if it does, I can see no version number, both in the list in my Applications folder, and when I click on Info. This is incredibly frustrating, and I'd sure like to know why many apps do not reveal their version number??? I have the preferences to show Size & Version number, yet half of them at least, just don't show up in the folders...
