Thanks. The other part is — Now how do I make it simply open with the most recent and then clear up any problems myself?
(1) You can make an alias of each application and put them on your desktop. Or you can drag an alias of the application to the Dock. Then drag your file over the alias and it will open in that application.
or (2) Right-click on the file and choose Open With and select the application you want to open the file in.
or (3) You can open the application first, and choose File > Open to open the file in that application.
I am not sure I agree on #3, unless there is another step.
