Open a project in a new window in IntelliJ after "accidentally" clicking remember decision

I wanted to open a new project in a separate window in IntelliJ and I "accidentally" clicked "Remember this decision and don't ask again" and clicked "open in the same window"!

Since I have more than one project it is getting really annoying to switch! Where could I change this setting?

Solution 1:

It can be changed in in File | Settings/Preferences | Appearance & Behavior | System Settings | Project Opening (or, before version 15, File | Settings/Preferences | General | Project Opening)

Solution 2:

In addition to the previous answers by Peter and Trailing Slash, Ctrl-clicking on a project in the "recently opened" list (File > Reopen Project) will open it in a new window - at least on Windows, running IntelliJ 14.0.3 Community edition. Useful if you only want to open a new window from time to time... :)

Unfortunately, this doesn't work with File > Open...

Solution 3:

In IDEA 14 and IDEA 15, this can be found in Settings | Appearance & Behavior | System Settings -> Project Opening.

Solution 4:

In IntelliJ IDEA 2016.x you can find it by path:

IntelliJ IDEA
  -> Preferences
    -> Appearance & Behavior
      -> System Settings : Project Opening preferences
