    I can not open two windows at the same time, from different applications in Mountain Lion. For example, if I want the & Omnifocus open, it will minimize the window that normally would be behind the newly opened window :mad:

    Installed any additional software lately?

    Open Activity Monitor and select All Processes and then sort by Process Name and then press CMD+P to print the process to a PDF, which you can attach here via the [​IMG] button.
    You can deselect other columns if you want, like your user name and such.

    Is it possible one of the apps is opening in full-screen mode?

    I have not installed any additional software lately, and I disabled my keyboard maestro macros...

    Sounds like you have Single Application Mode enabled. Follow the instructions at the end of this article to disable it:

    Do you have someone mischievous who has access to your Mac? It isn't something you can really enable by accident.
