    Description

      1- Under CentOS 5.3, double-clicking a Qt project opened project in a new Qt Creator instance which is expected behavior.

      • Under Vista, double-clicking a *.pro project file displays the following Qt dialog behaving as if it had been launched with the --client option while it had not.

      The dialog text:

      "Could not send message"
      "Unable to send command line arguments to the already running instance.
      It appears to be not responding. Do you want to start a new instance of Creator?"
      "Yes, Retry, No"

      At the time dialog is displayed, the project had already been added to my previous instance of Qt Creator. Answering Yes will start a second instance after which now have the same project open in two instances of Qt Creator; the original instance and the new instance.

      Steps to Reproduce
      ------------------
      1 - Create 2 Qt Projects in their own folders on the C: drive
      2 - Close all Qt Creator instances
      3 - Double-click the project1.pro file and verify first Qt Creator instance opens project1
      4 - Double-click the project2.pro file and verify that one of the following occurs:
      4.1 - project2 is opened in first instance of Qt Creator along with project1
      4.2 - A dialog may appear asking "Do you want to start a new instance of Creator?" even though it has already opened project2 in the first Qt Creator instance.

      CentOs 5.x or RHEL 5.x work as expected opening the double-clicked project in a new instancw.
