I recently upgraded from a couple of versions down to the latest version of PHPStorm. After restarting the app I can no longer open multiple files in tabs.
The way it used to work is that I would double click on a file from the project tree and it would be opened in a tab, then I could open a different file and it would open up in a new tab.. now, if I double click on a file it opens in a tab, then I double click another file and it replaces the previously opened file in the tab -- so I can't get multiple tabs open at the same time, it's just that single tab all the time.
Now, if I modify the file in the open tab, and then double click another file, it will open in a new tab.. but this doesn't work for me because it would be a pain to keep modifying files just to have them all opened.
Anyone knows if there's a setting that controls this? I tried enabling and disabling the preview tab feature -- which also doesn't work the way it should anyway.
