Recently when I'm working in Illustrator (v. 25.4.1) which I access through a shortcut on my desktop, and I open a second AI file that is saved on my computer, the saved file opens in a second/another session of Illustrator (v. 26.0.1).
I wonder if in the most recent update (whenever that was???), if the program was updated but it didn't replace/delete the previous version of the program. And now when I open a saved file, it opens in the most current version -- not the version that I'm working in.
And if I'm correct, what do I do? Do I uninstall v. 25.4.1? And can I be confident that none of my saved files are affected??? Is there any reason to keep v. 25.4.1 and NOT run v. 26.0.1 (because of bugs, glitches, etc)?
I would appreciate any advice you have.
