Unitron opening blank documents

I've tried looking for the answer here and on google, but I have been unable to find it. I just recently upgraded Unity to the newest version. However, every time I double-click a script file, Unitron will open up and display a blank document as opposed to the file I double clicked. This never has happened before. Has anyone experienced this issue before? And if so, is there a fix?

Thanks!

oh! figured out a work around. double click the file and then go to Documents → Previous Document to go the document you double clicked.
